2. It is made by mixing a small quantity of air-entraining agent or using air-entraining cement.
3. This concrete is particularly suitable for places where there is a greater chance of frost attack.
4. Its unit weight is less than the ordinary concrete but more than the lightweight concrete.
Lightweight Concrete
1. The concrete whose density varies from 300 to 1800 kg/m is known as lightweight concrete.
2. It is prepared by adopting any more of the following measures:
- a) By cellular construction.
- b) By using no fines concrete.
- c) By using lightweight aggregates such as expanded clay, shale and slate, fly ash, blast furnace slag etc.
