High-Performance Concrete
Definition:-
HPC is a concrete that has been designed to be
more durable and if necessary, stronger than
conventional concrete.
HPC mixtures are essentially composed of the
same materials as conventional concrete
mixtures. But the proportions are designed or
engineered to provide the strength and durability
needed for the structural and environmental
requirements of the project.
