Lightweight Aggregate
Natural lightweight aggregates, made from volcanic rocks, can be used after crushing and sieving. Their density ranges from 500 to 900 kg/m3 [26]. Examples include pumice, diatomite, scoria, and volcanic cinders. Artificial lightweight aggregates include expanded perlite, ed slag, expanded shale, and slate [18].
