What Is Lightweight Aggregate Concrete And Its Uses?

The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape. The shape and texture can directly affect its workability. The compressive strength level which is required by the construction industry to design strengths of cast-in-place, precast or prestressed concrete is known to be 3000-5000 psi. It is something that can be easily achieved ...

Lightweight concrete

The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete.

Lightweight Aggregate - an overview ScienceDirect Topics

It can be used as an aggregate for lightweight concrete making, owing to its low density and high porosity. The slump of lightweight geopolymer concrete with an aggregate from bottom ash is lower than in normal geopolymer concretes, owing to its rough surface texture, high porosity, and irregular shape of its particles compared with crushed limestone. The high friction of its particles ...
