Concrete Mix design calculation of M20, M25, M30 grade of concrete with example. ... In the present example against mild exposure and for the case of reinforced concrete the minimum cement content is 300 kg/m 3 which is less than kg/m 3. Hence cement content adopted = kg/m 3. As per clause of IS: 456.
Cementitious materials for concrete are fine mineral powders. When these materials are mixed with water, they react chemically to form a strong rigid mass that binds aggregate particles together to make concrete. The cementitious materials dealt with in this leaflet are all based on portland cement and many contain a "cement extender."
