UHPC achieves its superior performance through a dense nano-scale matrix that is far less permeable than conventional concrete. This matrix is combined with steel fiber reinforcement, which provides exceptional ductility and crack resistance.

Though exact formulations and results vary by producer, UHPC generally incorporates a blend of Portland cement, sand, supplementary cementitious materials, chemical admixtures, and fibers – resulting in a material dramatically stronger, tougher, and longer lasting than traditional concrete.
