1.3.1 ADVANTAGES OF HPC BRIDGES

Overall, the advantages accruing from higher durability and/or additional strength include a variety of benefits:
• Longer service life thanks to higher durability and lower chloride penetration. When needed, bridge life can extend to 100 years or even more.
• Lower maintenance and inspection requirements, especially since the bridge requires no painting or rust protection. This savings grows with the bridge’s longer service life.
• Longer spans, which can reduce costs by eliminating piers or allowing the use of concrete..................[:=> Show Contents <=:]

A comparison between experimental and calculated strains is shown in Figs.18 and 19. A simplified model was used for strain calculations; every two spans were assumed to be a continuous beam, although, joints constructed between spans do not guarantee full rigidity. Load distribution factors were obtained according to AASHTO provisions and axle loads were distributed accordingly.

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 stre..................[:=> Show Contents <=:]

INTRODUCTION

High performance concrete is a concrete having low water binder ratio. A value of 0.4 is suggested as boundary between usual concrete and high performance concrete.
It has high strength and durability. For high durability low permeability is required and to reduce permeability silica fume is used
