HIGH PERFORMANCE CONCRETE (HPC) – A SOLUTION TO VARIOUS PROBLEMS

Shibu O.K

INTRODUCTION


High performance concrete (HPC) can be considered as a logical development of cement concrete in which the ingredients are proportioned and selected to contribute efficiency to various properties of cement concrete in fresh as well as hardened states.
High performance concrete (HPC) is defined as a concrete mixture which posses high workability, high strength, high modulus of elasticity, high dimensional stability, low permeability and resistance to chemical attack.
There is a little controversy between the terms “high strength concrete” and “high performance concrete”. High performance concrete is also a high strength concrete but it has a few more attributes specifically designed as mentioned above. It is there for logical to describe by the more widely embracing term “high performance concrete” (HPC).
