- •
The effect of casting temperature on strength and denseness of plain and blended cement concretes has been studied.
- •
The optimum casting temperature for OPC and SF cement concrete is 32 °C.
- •
The optimum casting temperature for fly ash, very fine fly ash, natural pozzolan and blast furnace slag is 38 °C.
- •
Equations relating casting temperature, period of curing and strength and pulse velocity have been developed.
