ULTRA HIGH PERFORMANCE CONCRETE

Ultra High Performance Concrete

Ultra High Performance Concrete is defined as concrete that has a minimum specified compressive strength of 150 MPa with specified durability tensile ductility and toughness requirements; fiber are generally included to achieve specified requirements as per ACI 239R-18.

Ultra High Performance Concrete is known as reactive powder concrete.The material is typically formulated by combining Portland cement, supplementary cementitious materials, reactive powders, limestone and quartz flour, fine sand, high-range water reducers and water ranging from 0.15 to 0.25.The material can be formulated to provide compressive strength in excess of 29000 pounds per square inch (psi) (200 MPa). The use of fine materials for the matrix also provides a dense, smooth surface valued for its aesthetics and ability to closely transfer form details to the hardened surface.
