Ultra high performance concrete (UHPC)

Ae-uhpc, coarse aggregate UHPC product, expansion ≥ 600mm, 1-day compressive strength ≥ 90Mpa, 7-day compressive strength ≥ 150MPa, breaking the technical monopoly of SBT.

Ultra High Performance Concrete (UHPC), is a high strength, ductile material formulated by combining portland cement, silica fume, quartz flour, fine silica sand, high-range water reducer, water, and steel or organic fibres. The Construction Materials provides compressive strengths up to 29,000 pounds per square inch (psi) and flexural strengths up to 7,000 psi.

The ductile behaviour of High Strength Concrete is a first for concrete, with the capacity to deform and support flexural and tensile loads, even after initial cracking. The use of this material for House-building formwork system is simplified by the elimination of reinforcing steel and the ability of the material to be virtually self placing or dry cast.
