The demand for recycled fine aggregates (RFA) is increasing daily, and researchers are continuously looking for cheaper and local alternative fine aggregates. The increasing growth of municipal solid waste (MSW) incineration plants has led to the accumulation of incinerated bottom ash in the vicinity of cities. There can be a possibility to utilize...
This study presents an investigation of the effects of the precursor, alkalinity and temperature on the rheology and structural buildup of alkali activated materials. Here, 100% fly ash, 100% slag and blended mixes of fly ash and slag were activated by 4 M, 6 M, 8 M or 10 M (only for sodium hydroxide) solutions at 25 �C, 35 �C, 45 �C and 55 �C. The...
Stone processing wastes, being inherently colored, present an attractive option to develop the building façade products. In this study, four different types of stone processing wastes are characterized using X-ray diffraction, FTIR & Raman spectroscopies, and their suitability is evaluated to develop the colored bi-layered bricks. The stone process...
This study analyzed the last 20 years` data available on power plant coal ashes used in clay brick production. The statistical analysis has been carried out for a total of 302 cases based on the relevant parameters reported in the literature. The chemical composition of the clays and coal ashes, percentage incorporation and maximum particle size of...
Increased efficacy of fiber incorporation in self-compacting cementitious mixes (SCM) (mortar and concrete) has resulted in increased demand for virgin fibers. Production of virgin fibers consumes natural resources, which is an environmental concern. Researchers have investigated different waste originated fibers as an alternative to virgin fibers...
The present study demonstrates the mixing process of lime stabilized fly ash bricks. In India, fly ash bricks are gaining popularity against fired clay bricks due to their green benefits. However, the lack of technical guidelines on mixing methodology, and disproportionate moisture content in raw materials adversely affect the performance and produ...
The improper disposal of waste rubber tires leads to severe environmental and health issues, which can be mitigated through the use of waste tire rubber particles as construction material. In the present study, use of fiber shaped rubber particles has been explored as fine aggregates (up to 25%) in self-compacting mortar (SCM). Fresh state properti...
Expanding the capabilities of Raman scattering as an analytical tool for engineering applications can optimize the technological output immensely. Understanding the homogeneity of any blended mix is one such significant parameter in the family of composite building construction materials that needs an appropriate tool for its measurement. Raman spe...
Manufacturing of unfired bricks, in which fines are stabilized using cementitious or chemical binders, has huge potential to incorporate various wastes as a building construction material. Although researchers have successfully attempted various wastes in unfired bricks at the laboratory scale, their industrial-scale incorporation is still limited...
The productive utilization of the vast amount of industrial ash generated is of economic and environmen-tal importance. The use of industrial ash in brick manufacturing gives the two-fold advantage of thereduced cost of fly ash bricks as well as efficient disposal of industrial ash. However, due to variationsin chemical characteristics in the vario...
The proper management of a vast amount of natural stone waste generated from various stone processing industries of economic and environmental importance. The current study characterizes four different types of sludge stone waste to understand their potential as building material. The different types of stone wastes were characterized using Raman s...
The proper management of a vast amount of fly ash generated by various industries is of economic and environmental importance. The current study characterizes six different types of fly ash to understand their potential as a building material. The different types of fly ash were characterized by employing X-ray Diffraction (XRD) and identifying the...
This study focuses on the acid resistance of fine bone china ceramic aggregate (FBCA) concrete. Natural sand was partially and fully replaced by FBCA. The concrete specimens were exposed to 3% sulphuric acid solution up to 180 days. The main parameters identified were change in mass, compressive strength and microstructural changes. The changes in...
The force generated by a jet of water deflected by an impact surface is measured and compared to the momentum change of the jet. The experimental apparatus consists of a water nozzle, a set of impact surfaces, a spring scale connected to a balance beam, a flow meter, and plumbing for recirculating the water. The objective of this experiment to demo...
It is well known fact that drinking water is in scarcity and it will become a major problem for our society in times to come.Harnessing the drinking water also consume enormous amount of electricity. Rain Water Harvesting becomes very important because it can not only meet the minimum drinking water requirement of future generation but also saves e...

I observed sometimes self condensation in alkali activated solution without adding any precursor. I mixed 10 M NaOH solution and liquid sodium silicate (Modulus - 2.94 - 3.73) in 1:1 by weight ratio. Next day after 24 hours while going for test, I stirred the activating solution manually in beaker for 30 s - 60 s, and it went into self condensation and get convert into a white thick wax like material within 15 minutes` time.
Can any one suggest me the probable cause behind this?
In a typical situation, different layers of a product are designed to serve specific functions. Can we term this multi layered product as functionally graded product?
I need help to search technical standards related to fly ash bricks and fly ash in different countries. I have the Indian standard (IS 3812 and IS 15648) and American standard (ASTM C 618) related to fly ash and Indian standard (IS 12894 and IS 13757) and American standard (ASTM C 1790) related to fly ash bricks with me. I am searching for Euro codes, Japanese codes, Turkish Codes, Australian codes and Japanese codes mainly.
As per ASTM C67, I have conducted boiling test for different duration i.e. 1 h, 2h, 5h and observing shift in the trends. Can anyone explain the significance or difference between cold water immersion and boiling water test ?
I have the data of adsorption and desorption curve at relative pressure from 0.10 to 0.99 at every 0.10 interval. Can anyone guide me how I can calculate the total pore volume of concrete samples.
I want to perform BET surface area analysis of different fly ashes obtained from different sources. I require sample degassing conditions such as Target Temperature(c), Rate (c/min), Soak time (min.). Also what gas mixture should be used for experiment ?
I have mixed NaOH and Na2SiO3 24 hours prior to casting. Sometimes, when I shaked the hardner just before casting, it suddenly hardened in a dense viscous white material. Some time when I used the hardner with 48 hours premixed conditions, I found little settlement in glass flask.
This phenomenon is not always. I faced this occasionally.
I want to evaluate the effect of mixing stratagies on fresh mix of fly ash brick. Is there any direct method to check the homogenity of geopolymer brick mix?
I am working on geopolymer mix and want to identify the optimum liquid content to obtain maximum density, indirectly maximum compressive strength.
I want to determine fineness in terms of specific surface area for different materials such s fly ash, OPC and PPC cement using blaine air permeability apparatus. Should I need to determine separate K value for all materials using respective standard samples or using any one of them? My doubt is whether constant K remain same for instrument or it takes different values for different materials.
