I. INTRODUCTION
Nowadays, worldwide development of construction work
and the new technology, it is essential to fulfill the
requirement of urbanization. In most of the construction
material fine aggregate are common. As they are natural
resources the scarcity of sand is a great matter of concern to
save the natural resources.
On the other hand quarry dust which is a byproduct of
quarry plant. It is creating problems of disposal and also
reduces fertility of the land. As the quarry dust and fine
aggregate having nearly similar physical and chemical
properties, quarry dust can be replaced by natural sand in
construction material. It is available in large quantity and
also economical.
Mortar is used as a binder material to fill joints of bricks,
concrete cubs, plastering. So, using this waste as a partial
replacement of sand in mortar will give better strength,
durability, more workability.
Inclusion of bacteria will also increase the strength of
mortar. As the name suggest; bacterial cement mortar is the
mortar made with incorporating various types of bacteria
into it. Different types of bacteria’s can be used for
improvement of the various mortar properties like
improvement of strength, improvement of durability, as well
as permeability.
II. CRITICAL LITERATURE REVIEW
Following are the critical literature reviews on the paper of
treatment plant sludge.
Stocks-Fischer et al. (1999) has studied that nonpathogenic
soil bacteria B.pasteurii will have favorable calcite
precipitation and achieve high alkaline pH by urease
activity. They found that, the crystal of calcite precipitation
will fill the crack in mortar and also repair the subsurface of
porous media. [5]
Ramachandran et al. (2001) studied that using B.
pasteruii, remediation of cracks and fissures in concrete
utilizing microbiologically induced calcite (CaCO3)
precipitation. They also found out the effect of different
apportions and efficiencies of bacteria when suspended in
different media like water, phosphate-buffer and urea-CaCl2
on the workability of concrete. Conclusion of the study is
that the presence of bacteria in different media increased the
resistance of concrete towards alkali sulphate, freezethaw
attack and drying shrinkage. [14]
Ghosh et al. (2005) studied the strength chracteristics of
cement mortar with inclusion of an anaerobicbacteria at diff
proportion. The test results showed found that the
inclusionof an anaerobic hot spring bacterium in
mortar/concrete gives the increase in the compressive
strength by about 2530%. He concluded that at 28 days
curing period the strength of mortar increased 25% by
adding 105 cells/ml of anaerobic microorganism
(Shewanella sp.) mixed with water. But using Escherichia
coli microorganisms they did not find desirable increase of
strength of mortar. [8]

Bali et al, (2007) has studied the mechanical properties of
cement mortar by replacing the fine aggregate with artificial
sand of waste bricks. He replaced sand at various ponderal
contents 0, 25, 50, 75,100 %. and concluded that the mortar
gives desirable increment in compressive strength at the
25% replacement of sand by waste bricks. [7]
Willem et al. (2008) has focused on the possibility of
using bacteria foe carbonate precipitation for treating the
cracks of surface of construction materials like concrete,
mortar etc. he reached on the conclusion that bio-
decomposition shows the increase in the durability of the
mortar and concrete specimen. The test result shows that the
water absorption of the sample decreased due to inherent
porosity of CaCO3 crystals and also decreased the
carbonation rate by 25-30%. [27]
Anupama et al. (2010) has found out the viability of
replacing quarry dust in concrete and mortar. Bur quarry
dust has the finer particles, will increase the water cement
ration. He also noticed that it will decrease the strength of
mortar. In concrete and mortar for improvement of strength
at high water cement ratio, the addition of super pozzolanic
supplementary cementing materials likr; silica fume, rice
husk ash, metakaolin etc. will help. He concluded the in
mortar specimen where the cement is replaced by
metakaolin and quarry dust is replaced by natural sand,
gives the better results of strength and controlled water
cement ratio is achieved. [4]
Van Tittelboom et al. (2010) have used the ureolytic
bacteria such as Bacillus spaericus for biological repair of
cementicious materials. As the bacillus sphaericus has the
property of precipitating CaCO3 by converting urea into
ammonium and carbonate. And he concluded that the
improvement of compressive strength in concrete is
achieved by the microbiological CaCO3 precipitation. [11]
Afifudin et al. (2011) has studied behavior of the
chemically modified B. subtilize (CMBS) in mortar. He
observed that CMBS will adsorb silicate and formed
calcium silicate hydrated gel. He said that using optimum
concentration of 106 cells/ml of CMBS will gives 28%
higher strength than the control concrete. Thus the
mechanisms of bio-deposition and bio-mineralization in
biomimetic has been initiated for different species of
bacteria, especially Bacillus sp. [1]
Mahzuz et al. (2011) has the main concern to found an
alternative of sand and minimization of waste by using
quarry dust in mortar as a replacement of natural sand. The
concrete made of stone powder shows higher compressive
strength of 14.7% than the normal concrete. On the other
hand, the value of compressive strength will increase also
by making concrete from brick chip and stone powder. [12]
Nagabhushana et al. (2011) had found that the increasing
urbanization will affect the environment. Thus, the of use
alternative materials like; recycled aggregates, fly ash,
manufactured sand, crushed rock powder etc. for fine
aggregates in concrete. Which will results in maintain good
environmental conditions by reducing waste and also will
conserve the natural resources. The study of a partial and
full replacement for natural sand of mortar and concrete by
Crushed Rock Powder (CRP) is done For different
proportions like; 20% 40%, 60%, 80% and 100% and the
strength and durability is investigated. [16]
Haque et al. (2012) has studied the performance of the
mortar when mixture of sand and powder sand is used. it
may give better result in terms of strength, If better quality
of powder sand and proper gradation of sand and powder
sand can be used For concrete. Moreover, the powder sand
is treated as waste it have economic value almost zero. He
concluded that it will minimize the waste and also the cost
of concrete if it is used in making of mortar and concrete.
[15]
Jadhav et al. (2013) has replaced the natural sand by stone
dust and investigate the water cement ration if mortar. He
also use various proportion as 1:2, 1:3 and 1:6 with water
cement ratio of 0.5 and 0.55 respectively to design the
mortar mixes. He concluded that the excellent compressive
strength of Mortar cube specimens were achieved with 50%
replacement of natural sand by stone dust. He has achieved
an attempt towards sustainable development to find viable
solution to the declining availability of natural sand to make
eco-balance. [18]
Hoqeu et al. (2013) has focused on the comparison
between fresh mortar and modified mortar and also
replaced the natural sand by stone dust in cement mortar.
The strength of mortar containing 25% stone dust is higher
than normal mortar containing only sand. But the
replacement of cement results in the decrease of strength of
mortar. So it can be concluded that, stone dust can be
replaced by natural sand but not for replacement of cement.
Stone dust has a potential to provide alternative to fine
aggregate minimizing waste products. Thus the stone dust
will introduced as a functional construction materials. [25]
Raihan et al. (2014) has studied that the Stone dust
passing by No. 200 sieve, was used as cement replacing
material. The portion of dust which was retained by No. 100
sieve was separated to substitute sand and the remaining
part of dust was made finer by abrasion machine.. The
strength of modified mortar was investigated through
replacing of 20%, 30% and 40% of fine aggregates as well
as replacing of 5% of cement by stone dust. Several
numbers of cube and briquette samples were casted with
aforementioned proportions to investigate compressive
strength and tensile strength respectively and tested at 7
days and 28 days. From tested results, it was found that,
compressive strength of sample which has 30% of Stone
Dust and 0% of Cement replacement increases around 12%
& 17% respectively than the normal mortar sample at 7 &
28 days while for tensile strength it was increased 8.7%.
[19]
Senthilkumar et al. (2014) has investigated microbial
methods using EB bacteria and the nutriment on the surface
of the cement mortar specimens, creating a
microenvironment for growth and reproduction of bacteria.
Thus a calcite layer is gradually precipitated on the surface
of the cement mortar specimens after 7 days which reduced

its capillary water absorption in the BCGS1 cement mortar
specimen up to 13 times in comparison with the untreated
cement mortar specimen. The results shows that it was
possible to apply a bio-film (CaCO3 layer) at a desired
location and cracks also were cured in the existing building.
Then the acid attack is also considerably reduced. So
microbial technique provides the basis for an alternative and
high qualities cement mortar sealant with cost effective and
eventually will enhance the durability of the building
materials. [22]
Senthilkumar et al. (2014) has reported the effects of
bacterial carbonate precipitation on the compressive
strength of cement mortar specimens. He has studied and
analyzed the Physical and biochemical properties of cement
mortar when Enterococcus sp. microorganisms are added
and CaCO3 precipitation occurred. In the end he concluded
that a noteworthy enhancement of compressive strength
45% is observed in the Enterococcus sp. treated bio curing
specimen while compared to control. [23]
Sankh et al. (2014) has presented a review of preparing a
cement mortar with the different alternatives to natural sand
and studied the physical and mechanical properties and
strength. He observed the increase of strength in mortar
while sand is replaced by GGBS. This increase is not
significant. But for 100% replacement the strength
decreases a little bit but for 75 % replacement a desirable
strength is achieved. [3]
Maheswaran et al. (2014) have used the Bacillus cereus
and Bacillus pasteurii in different cell concentrations for the
experimental investigation on cement mortar. Test results
showed that the compressive strength was increased of
cement mortar due to the bio-mineralization of calcium
carbonate in the cement mortar matrix by the addition of
bacterial cultures of both species. The test results revealed
38% increase in compressive strength using B. cereus and
29% increase in the case of B. pasteurii. [14]
Lakhani et al. (2014) has showed that the replacement of
cement by stone waste such as limestone, marble and
marble with granite stone waste etc. decreased the
compressive strength of the resulting concrete/mortar due to
less binding effect and increased with sand replacement due
to filler effect. For different proportions of replacing cement
by 0, 50, 100,150, 200, 250 and 300 kg/m3, it was
determined that the Compressive strength at the 28 days for
the hardened concrete specimens had decreased. It was
concluded that the use of stone waste as a partial
replacement for sand will cause the great improvement of
the concrete and mortar structures. [20]
Thirougnaname et al. (2014) has investigated the
feasibility of unseived stone dust as fine aggregate in place
of river sand in making cement mortar 1:3, 1:4, 1:5 and 1:6,
which are the mixes usually adopted in various construction
activities. It is concluded that the compressive strength at 28
days of unseived stone dust used as fine aggregate in mortar
gives 5% higher strength for the ratio of 1:4, 1:5, and 1:6,
whereas 5% less than the conventional mortar for the ratio
1:3. Therefore the unseived stone dust in raw form can be
confidently used as a good construction material in making
mortar and that a maximum of 10-13% of fine materials i.e.
less than 150 micron in the unseived Stone dust may not
affect the strength of the mortar. [24]
Rajput et al. (2014) has studied the feasibility of using
crushed stone dust as fine aggregate in concrete and mortar.
The physical properties of stone dust and sand like bulk
density and specific gravity are similar. He concluded that
the workability of mortar showed better results when river
sand is replaced with stone dust. The mortar with the sand in
the flow rang of 85% do not gave high Compressive
strength than that of mortar with Crushed stone dust. [21] `
Kumar et al. (2015) has investigated the different
properties of cement mortar by replacing natural sand by M-
sand. He studied the cement mortar of 1:6 ratio of cement
sand and sand was replaced by M-sand at various
replacement and Strength and workability characteristics
were compared to normal cement mortar. The test results
showed that the strength and workability of mortar will
increase by replacing sand up to some level and decreased at
complete replacement. [17]
Maza et al. (2015) has studied the potential of making
mortar with binary sand in order to improve the physical
properties of sand. The increase in the quantity of mixing
water generated by addition of quarry waste was modified
by the addition of a super plasticizer or water reducing
admixture. The inclusion of crushed sand at replacement
levels of 40 % to 50% resulted in a increase in the
mechanical strength of the mortar. However, the improved
performance was observed when quarry waste as fine
aggregate was used in presence of chemical admixture (1%
of med flow 30). [13]
Ghoghare et al. (2015) has indicated that 25% replacement
level exhibit higher strength than the controlled sample and
the compressive strength of mortar is increased when using
stone dust as sand replacing material. But the strength get
decreased by the replacement of cement. Quarry dust at
25% replacement increases compressive strength but exceed
than 35% replacement decreases strength. Compressive
strength is increasing in addition of stone dust and by use of
metakaolin. The partial replacement of sand in mortar with
different proportion and with different water cement ratio
proves that it can be due to the extra fineness of quarry dust.
[6]
Ghogare et al. (2016) has studied that in case of cement
mortar, the naturally occurred sand can be replaced partially
by Stone by different proportion like 10%, 20%, 30% &
40%. The strength of mortar in 1:4 ratios, mortar containing
40% stone dust has given much higher strength than normal
mortar containing only sand as fine aggregate. For rich
mortar mixes, stone dust can be replaced up to 40%. Hence,
stone dust can be effectively used to replace natural sand,
without reduction in the strength of mortar with stone dust
replacement level up to 40%. [2]
Sahoo et al. (2016) has found that the Ureolytic-type
bacteria such as Bacillus sphaericus has been used to
improve the properties of cement mortar by the precipitation

of calcium. The presence of bacteria could not affect the
setting time of mortar. It is found that at 28 days of curing
period of mortar cube it would increase compressive
strength with the increase of bacteria concentration. He
concluded that the average compressive strength increases
by 58% (at 7 day) and 23% (at 28 day) over the control
specimen, at the optimum bacteria dosage of 107 cells/ml.
The sorptivity coefficient decreases as the concentration of
bacterial cells increases. The mineralogy and morphology of
the calcium carbonate precipitation have been tested by
XRD and FESEM. [10]
III. CONCLUSIONS
Based on Literature Review the following conclusions are
drawn:
The alternative ways are found out to replace the natural
sand to prepare the sustainable mortar and a step to utilize
the waste and reduce the use of natural resources was taken
into account. A waste product of quarry plant, stone dust is
economical and available in large quantity. Stone dust can
be replaced which is passing through IS sieve no. 100 as a
fine aggregate in mortar. At different proportion quarry dust
is replaced like 20%, 30%, 40%, 50%, 60%, 70%, 80% and
100%. But the best results showed at 40-70% replacement.
This sustainable mortar have the better properties than the
normal mortar and also economical. In addition for more
strength bacteria can be included in the mortar which will
do calcite precipitation and also protect from acid attacks.
The test results revealed that B. pasteurii bacteria will give
29% increase in strength of cement mortar than the control
cement mortar. At the optimum bacteria dosage of 10
cells/ml, maximum compressive strength increases by 58%
(at 7 day) and 23% (at 28 day), is achieved over the control
specimen.

... It has also been observed that concrete resistance to sulphate attack was enhanced greatly by the addition of quarry dust in concrete, which makes the concrete a greener one thereby to reduce environment pollution and improve durability of concrete under severe conditions [21]. Later, a study conducted by Patel and Pitroda revealed that 40-70% replacement is possible by means of quarry dust for getting better results and even more strength can be obtained by the addition of bacteria in concrete [22]. Further, it has been observed that reutilization of quarry dust from quarrying industry makes a justifiable tactic in order to conform with forthcoming requirements of conservational and concrete technology [23]. ...

There is a wide growth in construction industry in recent years, which is a very important area of concern for all the stakeholders. There is a wide-ranging diminution of natural resources, especially river sand. Also, the current statistics shows that for the production of one ton of cement, there is a discharge of one ton of carbon dioxide, which creates lot of environmental pollution. This has directed the investigators to find a more sustainable solution. Hence this study is oriented towards the development of a new building material in foamed concrete, in which natural river sand is completely substituted with manufactured sand, which is being substituted partially with quarry fine dust, which is an industrial by-product. The production of alternate building blocks using fly ash, GGBS and quarry dust can be very effectively used for the overwhelming construction processes. The consumption of industrial by-products in foamcrete, compensates the deficiency of natural resources, which solves the disposal of the above waste materials and safeguards the nature. With the use of this foamcrete blocks (density less than 1800 kg/m ³ ) as infills, slender sections can be designed for the framed construction works. Correspondingly, the thermal insulation properties of foamcrete blocks make it more acceptable in the present construction scenario. This is an attempt to focus the attention to discuss the utilization of industrial wastes in construction blocks. It has been observed that the construction blocks, made with these industrial wastes, have similar strength and other characteristics as that of conventional bricks. The maximum attained compressive strength is 13.29 N/mm ² .

As the world’s population continues to grow at an alarming rate, cities are being built up at a rate that is detrimental to the environment. Sand, a natural resource, is a key ingredient of cement mortar, the most popular building material. The scarcity of fine aggregate is the primary worry as the demand for sand grows. Quarry dust is a by-product of quarrying. Quarry dust is generally 5–7% per ton crushing quarry aggregate. Before quarry dust is replaced with natural sand in cement mortar, the physical and chemical properties of the two are examined. However, it seems to have virtually the same qualities. Quarry dust and Bacillus pesteurii bacteria at various concentrations like 105, 106, 107, and 108 cell/ml are used to substitute natural sand in this study because Bacillus pesteurii may form calcium carbonate (CaCO3) as a filler material and serve as a binding element in cement mortars. Bacterial mortar has a higher compressive strength than ordinary mortar or sustainable mortar, according to this research. A 107 cell/ml cell concentration yields a compressive strength test result of 31.01 N/mm2. This way, a cost-effective and environmentally friendly cement mortar may be utilized to recycle trash and safeguard the environment.

Ureolytic-type bacteria has been used to improve the strength of cement mortar by the precipitation of calcium carbonate. In the present study Bacillus sphaericus has been used to improve the properties of cement mortar such as setting time, compressive strength and sorptivity. The setting time is found to be unaffected by the presence of bacteria. It is found that compressive strength at both 7-days and 28-days of mortar cube increases with the increase of bacteria concentration. At the optimum bacteria dosage of 10⁷ cells/ml, the average compressive strength increases by 58% (at 7 day) and 23% (at 28 day) over the control specimen. The sorpitivity coefficient decreases as the concentration of bacterial cells increases. The mineralogy and morphology of the calcium carbonate precipitation have been tested by XRD and FESEM.

The utilisation of stone waste, in the form of mineral admixture as a pozzolanic and non-pozzolanic material for mortar and concrete has received considerable attention in recent years. This interest is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement (PC) and sand consumption, the utilisationof which being environmentally damaging. Another reason is that mortar and concrete, which contain pozzolanic as well as non-pozzolanic materials, exhibit considerable enhancement in durability properties. This paper reviews work carried out on the use of stone waste as a partial non-pozzolanic replacement for sand in mortar and concrete and in the containment of hazardous wastes. The literature demonstrates that different stone wastes is an effective inert filler which causes great improvement in the pore structure and hence the resistance of the concrete to the action of harmful solutions.

Scarcity of river sand is one of the major problems in the construction industry. Studies were conducted to find out the feasibility of using quarry dust to partially replace sand in concrete.. These studies revealed that, due to increased fineness, the combination require an increased water cement ratio which results in strength reduction or the use of a water reducing admixture. Use of super pozzolanic supplementary cementing materials such as silica fume, rice husk ash, metakaolin etc in concrete and mortar improves the strength even at a higher water binder ratio. M etakaolin, a manufactured material, calcined kaolinite is available at moderate cost. This paper presents the results of a study to use metakaolin in cement mortar as a partial replacement of cement where quarry dust was used as the fine aggregate. The effect of water binder ratio and metakaolin replacement level on the compressive strength of cement quarry dust mortar was investigated.

This study was aimed to find the possibility of applying Bacillus subtilis integrated into mortar matrix as a self-healing agent to seal cracks. Bacterial spores at concentrations of 104, 105, and 106 cells/ml were directly added into pulverized fly ash as medium to protect bacteria in high alkaline conditions. The results show that the addition of Bacillus subtilis spores into the mortar mixture enhanced the compressive strength, especially at the cell concentration of 105 cells/ml. The bacterial mortar had a small ability to recover the stiffness of the mortar, amounting to 34.85% of its original stiffness. The effectiveness of crack sealant and resistance to water flow were limited to a maximum crack width size of 0.22 mm. Physical observation showed that the bacterial mortar is characterized by calcite precipitation as a product of ureolytic bacteria. The quantity and distribution of calcite precipitate depended on the precipitation weight, gravity direction and the oxygen availability. Meanwhile, chemical analysis using XRD and EDX showed that the bacterial mortar had a better crystallinity.

Natural river sand is widely used as fine aggregates in preparation of conventional cement mortar. Due to extraction in excess, natural sand has become a scarce material and it has to be preserved. Manufactured sand (M-sand) has very high potential to replace the natural sand in preparation of cement mortar. This research paper presents a study on replacement of natural sand in cement mortar by M-sand at different percentages. Strength and workability characteristics of 1:6 cement mortar using natural sand and M-sand as fine aggregate at various replacement levels were evaluated and compared. The workability of the cement mortar increases with the increase in M-sand content up to certain level, whereas the strength increases with the increase of manufactured sand. Hence M-sand can be recommended for the replacement of natural river sand in cement mortar.

Around 5% of worldwide CO2 discharges originate from bond generation. Gas outflow is the consequence of fuel ignition and compound responses that occur in various phases of the procedure, principally in the clinker blazing stage. Amid the procedure of bond assembling, around 0.92 t of CO2 is discharged per ton of clinker delivered. This discharge for the most part originates from decarbonization of limestone, and the utilization of carbon energizes for warming (0.39 t). Normal CO2 outflows take up with processing procedures are 0.1 t of CO2 for each ton of concrete and originates from creation of power. As ecological, transportation and different limitations make the accessibility and utilization of waterway sand less appealing, a substitute or swap item for solid industry should be found. The materials utilized incorporate Ordinary Portland Cement, quarry-tidy, waterway sand and water. Bond, Quarry clean and River sand are tried for their physical attributes according to the significant measures. The outcomes demonstrated that 30% substitution of quarry tidy gives more quality and it is appropriate for field works.

-Concrete in most structures is designed to crack in order to let embedded steel reinforcement take over tensile stresses. Crack formation is also a typical phenomenon related to durability. Percolation of cracks may lead to leakage problems or ingress of deleterious materials, causing deterioration of the concrete matrix or corrosion of embedded steel reinforcement. Durability can be enhanced by preventing further ingress of water and other substances. In recent years a bacteria-based self-healing concrete is being developed in order to extend the service life. A two component healing agent is added to the concrete mixture. The agent consists of bacteria and an organic mineral precursor compound. Self healing agents such as epoxy resins, bacteria, fiber are used to heal cracks in concrete. Among these, bacteria used in concrete are effective. When the bacteria is mixed with concrete the calcium carbonate precipitates forms and these precipitates filling the cracks and makes the crack free concrete. The state of art results in all projects show that material designed as self healing agents.

This experimental study investigates the effect of using binary natural fine aggregates (dune sand and crushed sand) on mortar. This method is utilized to modify the particle size distribution of various sands used in mortar. For this investigation, two sands were used: a dune sand (DS) and crushed sand (CS) at different proportions in mortar. The effect of the quality and grain size distribution of natural fine aggregates (DS ad CS) on the physical properties of binary sand confected (apparent or bulk density, absolute or gravity density, porosity, fineness modulus, particle size distribution and water absorption). The properties of fresh and hardened mortar were also analysed. The results obtained showed that the mechanical strength of mortar depends on the nature and particle size distribution of sand studied. This study shows the potential of this method to make mortar with binary sand (dune and crushed fine aggregates) in order to improve the physical properties of sand. The increase in the quantity of mixing water generated by addition of quarry waste was modified by the addition of a superplasticizer or water reducing admixture (Medaflow 30) what led to the improvement of the physical and mechanical properties of the mortar. The inclusion of crushed sand (CS) at replacement levels of 40 % to 50% resulted in a increase in the mechanical strength of the mortar. However, the improved performance was observed when quarry waste as fine aggregate was used in presence of chemical admixture (1% of Medaflow 30).

Concrete is a major building material which is used in construction throughout the world. It is extremely versatile and is used for all types of structures. Due to rapid growth in construction activity, the consumption of concrete is increasing every year. This results in excessive extraction of natural aggregates. The use of these materials is being constrained by urbanization, zoning regulations, increased cost and environmental concern. Thus, it is becoming inevitable to use alternative materials for aggregates in concrete which include recycled aggregates, fly ash, manufactured sand, crushed rock powder etc. The use of such materials not only results in conservation of natural resources but also helps in maintaining good environmental conditions. The present investigation aims in the study of properties of mortar and concrete in which Crushed Rock Powder (CRP) is used as a partial and full replacement for natural sand. For mortar, CRP is replaced at 20% 40%, 60%, 80% and 100%. The basic strength properties of concrete were investigated by replacing natural sand by CRP at replacement levels of 20%, 30% and 40%.

Microbially induced calcium carbonate precipitation (MICCP) is a novel method for the protection of cement-based materials. This paper deals the comparative studies on strength characteristics in microbial cement mortars which were treated by Enterobacter sp. M2 microorganism in different calcium source (calcium hydroxide, calcium acetate, calcium chloride and calcium oxide) with various curing process. The crystalline phases of calcium carbonate (CaCO3) crystals formation and the surface morphology of cement mortar were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). Cement mortar specimens with and without addition of bacterial species were casted and ~ 44% increase in compressive strength, ~56% in tensile strength was noticed while compared to control specimen (without bacteria). Surface treatment of specimen with bacteria resulted around ~40% decrease of water absorption and increases the resistance to water and hazard material penetration, mainly attributed to its pore blocking effects. This biological surface treatment shows promising prospect for increasing durability aspects of concrete/cement mortar.
