Litagg -Lightweight aggregates

LDA -Sintered Flyash lightweight aggregates  Lightweight Aggregates (akin low density aggregate) is a generic name of a group of aggregates for structural concrete, mortar, or plaster that weighs less than usual rock aggregates including natural sand, gravel, and crushed stones. At an earlier stage, lightweight aggregates were mainly from natural origin, mostly volcanic pumice, etc. It is production  begins with mining or quarrying the raw material and with the development of mining machinery and technology, they can be manufactured from the natural raw materials like expanded clay, shale, slate(expanded about twice the original volume of the raw material) as well as from the by-products such as fly ash, blast furnace slag, etc. However, the natural pumice, vermiculite, and perlite can also be used as substitutes. The expanded raw material(excluding pumice) has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete produ...
