The effects of the fly ash and of the sunflower stalks and corn cobs within a cement-matrix composite were studied under the aspects of density, compressive strength, splitting tensile strength, elasticity modulus, and resistance to repeated freeze-thaw cycles. In the research were developed 20 recipes of cement-based composite, including the reference composite. Fly ash was used as partial cement replacement (10, 20 and 30% by volume), and the vegetal aggregates made by corn cobs and sunflower stalks as partial replacement of the mineral aggregates (25 and 50% by volume). The study results revealed that a lightweight composite can be obtained with 50% of vegetal aggregates , and the fly ash, no matter its percentage, enhanced the compressive strength and splitting tensile strength of the compositions with 50% of sunflower aggregates and the freeze-thaw resistance of all compositions with sunflower stalks.

This work presents the results of the study of the physical, chemical, mineralogical and pozzolanic properties of the altered volcanic tuffs (AVT) that lie in the Los Frailes caldera, south of the Iberian Peninsula, and demonstrates their qualities as pozzolans for the manufacturing of mortars and pozzolanic cements of high mechanical strength. The main objective of this research is to show to what extent the AVTs can replace portland cement (PC) in mortars, with standardised proportions of 75:25% and 70:30% (PC-AVT). To achieve these objectives, three AVT samples were studied by a petrographic analysis of thin section (PATS), DRX, FRX and MEB. The pozzolanic properties were determined by three methods: electrical conductivity (ECT), chemical pozzolanicity tests (CPT) at 8 and 15 days and mechanical strength tests (MS) of the specimens at 2, 7, 28 and 90 days. Studies of a PATS, DRX, FRX and MEB showed that the AVT samples’ constitutions are complex where smectite (montmorillonite), mordenite, quartz, halloysite, illite, kaolinite, volcanic glass and lithic fragments coexist. The results of the ECT and CPT tests confirmed the pozzolanic properties of the samples analysed and proved an increase in mechanical strength from 2 to 90 days of testing.

Utilization of concrete in construction industry has increased in last decades. Although, concrete has a lot of advantages, it is important to consider its negative impacts on environment. One of that negative impacts is depletion of natural resources. To protect environment and make concrete industry sustainable it is needed to find alternative materials, which can be used in the concrete mixture. Agricultural sector has many wastes which would be proper alternatives in manufacturing sustainable concrete. This study presents experimental test results of a green concrete was made of coconut shell as an alternative for normal coarse aggregate in concrete mixtures for developing a sustainable lightweight aggregate concrete. From several trial mixes using coconut shell lightweight aggregates, it was possible to develop mix proportions for a structural lightweight aggregate concrete with good workability and a 28-dayay compressive strength of 38 MPa and density of 1986 kg/m.
... Another effective approach is the partial replacement of cement with pozzolanic materials, which has demonstrated positive outcomes in terms of durability [18,19] and sustainability issues associated with CO 2 emissions and other greenhouse gases [20]. Moreover, cement production is a highly energy-consuming process, accountable for up to 3% of global primary energy and 5% of total industrial energy [21]. Hence, supplementary cementitious materials also have the advantage of reducing energy consumption and lowering the costs of construction. ...

The mechanical response of sandwich panels with two layers of curauá fiber cement composites and a core layer of autoclaved aerated concrete (AAC) was investigated. Each layer consisted of long unidirectional curauá fibers and a cementitious matrix. For durability purposes, 50% of the Portland cement was replaced with pozzolanic materials to reduce the content of calcium hydroxide in the matrix. The performance of sandwich panels with 350 mm × 60 mm × 90 mm (length × width × thickness) was evaluated through monotonic and cyclic four-point bending tests to obtain the load–deflection response, flexural strength, and toughness. Monotonic bending tests were performed on each component of the panels – i.e., composites and AAC blocks. Pull-off tests were performed to evaluate the adhesion between the skin layers and the core, while optical and scanning electron microscopes were used to observe the interface's topography. The results revealed the externally bonded layers' efficiency, which provided a higher deflection capacity to the material and increased its flexural strength. The AAC blocks revealed a more ductile response when assisted by the composite layers in the sandwich structure. Under cyclic bending test conditions, the sandwich panels exhibited a satisfactory post-peak ductility so that the energy was not abruptly lost but gradually released throughout its deflection-softening behavior.

This research paper aims at investigating the effects of fly ash as cement replacement in green concrete made with partial replacement of conventional coarse aggregates with coarse aggregates from demolishing waste. Green concrete developed with waste materials is an active area of research as it helps in reducing the waste management issues and protecting the environment. Six concrete mixes were prepared using 1:2:4 ratio and demolishing waste was used in equal proportion with conventional aggregates, whereas fly ash was used from 0%-10% with an increment of 2.5%. The water-cement ratio used was equal to 0.5. Out of these mixes, one mix was prepared with all conventional aggregates and was used as the control, and one mix with 0% fly ash had only conventional and recycled aggregates. The slump test of all mixes was determined. A total of 18 cylinders of standard size were prepared and cured for 28 days. After curing the compressive strength of the specimens was evaluated under gradually increasing load until failure. It is observed that 5% replacement of cement with fly ash and 50% recycled aggregates gives better results. With this level of dosage of two waste materials, the reduction in compressive strength is about 11%.

A large number of concrete production today has a bad effect on environment resource and energy. Thus this issue of concrete technologies have an impact on the environment which is a critical problem in global warming. The current paper reviews the concrete technology and sustainable development from past to future and investigates sustainable concrete and material practice. Although while comparing these factors with the past, current and future prospective concrete sustainability development, this research found that the main cause of global warming is 〖CO〗_2 emission during concrete and cement production. The solution of environment problem is not to replace the concrete by other substances and it can reduce the amount of cement with cementitious materials. The best approach for reducing the amount of 〖CO〗_2 in environments is using Pozzolanic material and waste material, which both plays a vital role in the sustainable concrete structure.
... Additionally, it was reported that to produce one tonne of cement, 1.6 tonnes of natural resources and 4GJ of energy are consumed [12]. Altwair and Kabir [13] stated that cement consumption will grow at a high rate at world level in the 2000-2030 period according to the Business as Usual (BAU) scenario. Looking at this situation, limestone powder is one of the potential alternatives as a partial cement replacement. ...

Self-Consolidating Lightweight Foam Concrete (SCLFC) is known as a concrete which has no requirement towards vibration or compaction effort due to its flowability and capability in filling and achieving full compaction in reinforcement. The main component in SCLFC is cement. Cement is a basic component of concrete that used in construction industry. However, it is also the main source of Carbon Dioxide (CO 2 ) emission. If this component of concrete is replaced with other materials, it surely can help in reducing the emission of CO 2 . Limestone powder can be replacement with the cement content in SCLFC. Therefore, the aim of this paper is to determine the effect of limestone powder on SCLFC in term of flowability and compressive strength. The specimens were tested for compressive strength at 3, 7, and 28 days. The result indicated the flowability of SCLFC increase with the increase of percentages of limestone powder replacement. Meanwhile, the highest compressive strength of SCLFC containing 10% limestone powder replacement give better performance than the normal SCLFC. Based on the finding, SCLFC containing 10% limestone powder replacement can be categorized same as a conventional concrete hence it can be utilized for construction purposes. Limestone powder can also acts as an alternative replacement in concrete for replacing the cement.
... Slag usually increases workability and decreases the necessary water quantity due to increased volume of paste (increase in volume of the paste is determined by relatively low density of the slag) ( Li et al., 2016). To protect steel reinforcement, concrete with granulated slag requires a smaller thickness of the coating than conventional concrete due to lower permeability ( Altwair & Kabir, 2010a;Altwair & Kabir, 2010b). The same benefits have been reported when using silica fume or ash from fuel as supplementary material for concrete ( Awal & Hussin, 1997;Chindaprasirt et al., 2008;Rukzona & Chindaprasirt, 2009a;Rukzona & Chindaprasirt, 2009b;Tangchirapat, 2009). ...
