Lightweight Aggregate Concrete Properties, Uses and
Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m3, when compared to normal concrete which is 2300-2400 kg/m3 and a proportion of the aggregate, should []
Lightweight Aggregate Concrete an overview
The lightweight concrete aggregate or common concrete hollow block is used as the basic material. High-efficiency insulation materials (such as polystyrene material, slag, rice husk, perlite, and foam insulation materials) are used as filling materials in the holes of hollow blocks. The automatic process line is applied in which the block shells and insulation materials are molded together as

Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
