Lightweight Aggregate Concrete - an overview ...

1992-1-1 · Light-weight (aggregate) concrete ( ρ ≤ 1900 kg/m 3) is of smaller modulus of elasticity, sharp stress–strain curve, and fails suddenly (see Section 4.2 ). The mechanical behavior of the reinforced beam of light-weight concrete is similar to that of ordinary concrete, but shows larger deflection, wider crack, and quicker failure.

The concrete made by brick bat aggregate is not exactly the light weight aggregate concrete, but its weight is slightly less than normal-weight concrete. Brickbat aggregate are made with slightly over burnt bricks. Sometimes, for the manufacture of heat resistance concrete, brick bat aggregate is used in conjunction with high alumina cement.
