2012-6-7 LIGHT WEIGHT AGGREGATE : Preamble: InGlobal Resources, New Delhi focuses on sourcing advanced technology; which can produce artificial lightweight Aggregate (LWA) from fly ash, a waste product of coal burning power plants. The product is an excellent alternative to natural quarried aggregate
2021-3-16 This light weight aggregate is further classified as: i. Clinker Aggregate: It is called cinder in U.S.A. It is made from well burnt residue of industrial high temperature furnaces, fused into lumps. The clinker should be free from harmful varieties of un-burnt coal, which is a main source of unsoundness in the concrete made from this aggregate.
2019-7-1 Light weight expanded clay aggregate is made by heating clay to around 1200 degree celsius in kiln.LECA was first developed in Kansas in 1917 following which gravelite, perlite, rocklite etc were developed. Their sizes vary from 0.1mm to 25mm and densities of 250, 280, 330 and 510 kg/m3.
A light-weight aggregate comprising a pellitized agglomerated mixture of by weight 50 to 86 parts self-hardening fly ash formed in the combustion of sub-bituminous coal from the Powder River Basin 1 to 14 parts sulfate surfactant foam, 0 to 6 parts accelerator which is extract of silica fume dust, and 0-30 parts additive selected from the group

A light weight aggregate is described which is formed of fly ash and solids derived from the caustic extract filtrate produced in a kraft pulping process. In a method for producing the light weight aggregate caustic extract filtrate produced in a kraft pulping process is concentrated to a desired level.
light weight aggregate which was pre-wetted was used . instead of coarse aggregate in control mix. The same . procedure for casting and curing of control mix is .
Structural light weight aggregate concrete (LWAC) are usually produced by replacing a whole or a part of natural normal weight aggregate by artificial or natural light weight aggregate (LWA). Such aggregates, natural or artificial, are available in various parts of the world. Pumice is a type of
