LIGHT WEIGHT CONCRETE
- The concrete which has substantially lower mass per unit volume then the concrete made of ordinary ingredients is called lightweight concrete. The aggregates used are lighter in weight.
- Density of light weight concrete is 240 kg/m³ (15pcf) -1850 kg/m³ (115 pcf).
- Strength of light weight concrete blocks varies from 7 MPa (1000 psi) - 40 MPa (5800 psi).
- Some times Air Entrained Admixtures are also added to it giving resistance to freezing and thawing along with strength.
Uses of Light weight concrete:
- Used where extra load is not applied e.g. parapet wall, road lining etc. or to reduce dead load.
