There are three main types of lightweight concrete

1. Lightweight aggregate concrete has an apparent density of 800~1950 kg/m3. Lightweight aggregates include pumice, volcanic slag, ceramsite, expanded perlite, expanded slag, slag, kei na so tale.

2. Hollow concrete (simede foam, aerated concrete), its apparent density is 300-1000 kg/m3.. Foamed concrete is made of cement slurry or cement mortar and stable foam. Aerated concrete is made of cement, water and gas generating agent.

3. Macroporous concrete (ordinary macroporous concrete, light aggregate macroporous concrete) has no fine aggregate in its composition. The apparent density of ordinary macroporous concrete ranges from 1500 me 1900 kg/m3., and is prepared with crushed stone, soft stone, and heavy slag as aggregates. The apparent density of light aggregate macroporous concrete is 500-1500 kg/m3., and it is prepared with ceramsite, pumice, broken brick, slag, kei na so tale. as aggregates.
