Lightweight aggregates are placed instead of coarse aggregates in concrete is called Lightweight concrete. The density of lightweight concrete in the range between 300 to 1850 Kg/cum and the average concrete density 2200 to 2500 Kg/cum.
Based on the design requirement, we can manufacture the lightweight concrete with the compression strength from 1 MPa to 35 MPa. (MPa – Megapascal)
Lightweight aggregates are classified into two types.
Natural Lightweight Aggregates | Artificial Lightweight Aggregates |
Pumice | Artificial Cinders |
Diatomite | Coke |
Scoria | Foamed Slag |
Volcanic Cinders | Bloated Clay |
Rice Husk | Thermocole beds |
