Introduction
The use of high strength concrete (with f’c>50MPa) is very common in buildings and other structures designed recently. Economy, superior strength, stiffness and durability are the major reasons for its popularity. Structural Engineers are presently exploring the benefits of using this efficient material in various applications.
High Strength Concrete has compressive strength of upto 100 MPa as against conventional concrete which has compressive strength of less that 50 MPA. Concrete having compressive strength greater than 200 MPa is classified as Ultra high strength concrete. The ingredients of high strength concrete are the same as those used
