Mix-Design of high performance concrete (HPC) by using ...

Concrete is widely used as building material since its discovery. It is used to resist the compressive forces. Concretes have three major characteristics such as workability, strength and durability. The workability depends on the water cement (W/C) ratio. The strength of concrete also depends on the size and shape of an aggregate.
