Lightweight Aggregate Concrete: Types, Properties And ...

LWAC is the popular type of light weight concrete, in which lightweight aggregates are used. The lightweight aggregates are relatively new materials. These have a unit weight up to 12kN/m3. The LWA can be either natural or artificial or manufactured. The natural aggregates include volcanic cinder, dolomite or pumice.

Current design methods for structural lightweight aggregate concrete (SLWAC) are usually only valid for a limited range of concrete compositions that have previously been subjected to trial tests. The SLWAC mix design is more complex than that of normal weight concrete …

Mix design of light-weight self-compacting concrete ...

The addition of the mineral powders in the mix design to produce a flowable concrete is accompanied by the replacement of normal weight coarse aggregate with a light weight powder and light weight aggregate to produce a lighter concrete.

Lightweight concrete

Pumping lightweight concrete can be achieved, but care needs to be taken so that the concrete mix doesn't separate. For pumpable mixes it is usual to use a natural sand, i.e. not to have a lightweight aggregate for the fine portion of the mix and to have a high workability so that increased pump friction and blockage is avoided.
