High-performance concrete (HPC)
Concrete that has been designed to be more durable and stronger than conventional concrete is known as high-performance concrete (HPC). The materials used in HPC mixtures are generally the same as those in conventional concrete mixtures, but the proportions are designed, or engineered, to meet the structural and environmental requirements of a project. Concrete with a specified compressive strength greater than 8000 psi (55 MPa) is called high-strength concrete. We chose 8000 psi (55 MPa) as the strength level at which special care is required for the production and testing of concrete, as well as for structural design considerations.
High Performance Concrete is defined differently by numerous organizations and experts. The American Concrete Institute describes High Performance Concrete as “Concrete that satisfies unique criteria for performance and uniformity that cannot always be achieved by using traditional materials, standard blending method and typical curing methods”.
HPC is a concrete, in simpler words, with at least one outstanding property viz. In contrast to standard concrete, compressive strength, high workability, increased resistance to chemical or mechanical pressures, lower permeability, longevity etc. Self-compacting Concrete, for instance, is a particular part of High-Performance Concrete, which distinguishes itself with high flowability-coupled self-consolidation properties.
