Ultrahigh-performance cement-based composite material
The invention relates to an ultrahigh-performance cement-based composite material. Particle gradation of a polynary gelling material and particle gradation of aggregates are optimized, and a water reducer and other additives are used, so the compressive strength under 28d standard curing reaches 170MPa or above on the premise that concrete has good fluidity. The material has the following technical advantages: construction fluidity requirements are met under a low water-binder ratio; under standard curing conditions, the strength of the concrete in 7d age reaches 120MPa or above, and the strength of the concrete in 28d age reaches 170MPa or above; compared with RPC which only can be used to produce prefabricated parts, the composite material can be stirred and constructed in any occasions without hot curing or pressure forming; the impermeability, the carbonization resistance, the chloride ion penetration resistance and the freeze thaw cycle resistance of the composite material are better than those of common concrete; and the composite material can be used to produce member products with the cross section being 50% (or more) than the common concrete member products.
