Energysaving products:Fly ash LWA has an excellent thermal insulation property. The concrete made by fly ash LWA has thermal insulation ratio /, which is about 48%86% lower than regular concrete. Environmental Protection:Fly ash is a by product of coal burning power plant. Most of fly ash is dumped as waste material.
Saving in cement 430337 = 93 kg/m 3. It may be noticed that, for the fly ash concrete the total cementitious material is greater but the OP cement content is smaller, the fine aggregate content is reduced but the coarse aggregate content is deliberately the same, the water is reduced and the density is reduced because of the lower density of fly ash compared with cement.
Continuous manufacture of sintered flyash light weight aggregates. Application: As aggregate in concrete for lightweight construction works. Feature: The flyash nodules made with the help of water are fired at 1200oC. The fine particles of flyash melt at the surface and are welded together. The nodules crumble during the sintering process.
Fly ash can be used with Portland cement to improve the performance and workability of the concrete. Typical substitution rates are between 15 – 30%. Fly ash reduces the risk of sulfate and chlorine ingress as well as help to protect against ASR from certain aggregates.
Comparative assessments of natural aggregates with sintered fly ash aggregates were evaluated. Mix design was obtained by the IS method for M30 grade concrete, and within the natural aggregates were replaced with 20%, 40%, and 60% amounts of SFLWA. The addition of SFLWA shows an increase in the workability of the concrete.
Boral offers a technology and service for the manufacture of ceramic lightweight aggregate (LWA) from coal combustion products generated by current production or recovered from landfills or ponds. The resulting aggregate can be sold and beneficially purposed in a variety of construction, agricultural, and related applications.

fly ash is collected in a very finely divided condition in various types of dustcollecting systems, such as cyclone collectors or electrostatic precipitators. It is the purpose of this paper to describe the requirements for fly ash as used in the sintering processes and the properties of the fly ash aggregates that are produced.
production of artificial flyash aggregate is a suitable construction material, which could be made from fly ash. Artificial, sintered, flyash aggregate is one of the few construction materials that can be produced only with fly ash. European and worldwide trends of newly developed building technologies accentuate the demand for the
Sintered Fly Ash LWA was first made in 1961 in England The annual usage of LWA in the developed countries: about 80~100 millions m3 The annual usage of LWA in the Chinese market so far (clay shale): about 4 million m3. ANew Breakthrough of Technology From MeTech Inc SINTERED FLY ASH LIGHTWEIGHT AGGREGATE. Fly Ash Lightweight Aggregate FLY ASH ...
Adopted process uses above 90% fly ash mixed with water and in some cases a small volume of additives. After agglomeration and pelletizing, the green pellets are sintered at high temperature, producing light weight aggregate whose characteristics are similiar to natural aggregates.
Presently in India the power sector depends on coal based thermal power station, which produce a huge amount of fly ash approximately to be around 200 million tones annually. The mass utilization of fly ash in concrete, essentially focused on sintered fly ash aggregate replaced by natural coarse aggregate is thought of in this investigation.
Lightweight concrete with sintered flyash aggregates was compared with that of normal weight concrete with granite aggregates for various water/binder ratios starting from 0·30 to 0·50.
