What is Lightweight Concrete? -Types, Uses and Advantages

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³)Production Of Lightweight Aggregates Distroid Concrete,Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete Concrete production is timesensitive Once the ingredients are mixed, workers must put the concrete in place before it hardensLightweight concrete - concretecentre,Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3 Lightweight concrete can be specified using the notation LC for the strength class, eg LC30/33, which denotes a lightweight concrete with a
