What is High Performance Concrete?
High Performance Concrete (HPC) is a specialized series of concretes designed to provide several benefits in the construction of concrete structures:
|Performance Benefits||Cost & Other Benefits|
Several strength and durability criteria were used in the evaluation of HPC designs:
|Strength Criteria||Durability Criteria|
|Modulus of Elasticity||Scaling|
HPC is one of the four categories within the SHRP Implementation Program's Concrete and Structures section. Under SHRP, four types of High Performance Concrete were developed:
|HPC Type||Minimum Strength Criteria||Water-Cementitious Ratio||Minimum Durability Factor|
|Very Early Strength (VES)||2 000 psi / 6 hours||< 0.4||80%|
|High Early Strength (HES)||5 000 psi / 24 hours||< 0.35||80%|
|Very High Strength (VHS)||10 000 psi / 28 days||< 0.35||80%|
|Fiber Reinforced||HES + (steel or poly)||< 0.35||80%|
