CEMENT CONCRETE MIX DESIGN - Dronacharya

2015-9-15  FACTORS TO BE CONSIDERED FOR MIX DESIGN The grade designation giving the characteristic strength requirement of concrete. The type of cement influences the rate of development of compressive strength of concrete. Maximum nominal size of aggregates to be used in concrete may be as large as possible within the limits prescribed by IS 456:2000.
