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 sie of aggregates to be used in concrete may be as large as possible within the limits prescribed by IS 4562000.
1 meet the strength grade of concrete design. 2 meet the concrete peaceability. 3 meet the durability of the use of concrete. 4 meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades such as C7.5 C10 C15 C20 C25 C30 C35 C40 C45 C50 C55 C60 and so on.
