Lightweight Aggregate Concrete: Types, Properties And Factors Affecting Mix Design

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. The artificial aggregates can be blast furnace slag, sintered fly ash or bloated clay.


There exist minimum dimension of structural elements in civil engineering structures that have to be followed while designing and in implementation. It is irrespective of the codes and provisions. Minimum dimension is the value that has to be implemented how lower be the load conditions exist in that particular area.
