Concrete Mix Proportioning - civilengineering.blog

2017-10-29  Concrete Mix Proportioning : The determine of the proportions of cement, aggregates and water to attain the desired strength and properties such as workability, durability etc., is called as concrete mix proportioning. The design of concrete mix is classified into following two types by IS 456:2000 (Clause 9) : (1) Nominal mix concrete.
