Ultrahigh-toughness cement-based composite material and preparation method thereof

The invention provides an ultrahigh-toughness cement-based composite material. The ultrahigh-toughness cement-based composite material is prepared from 200 to 250 parts of cement, 500 to 550 parts of solid wastes, 200 to 250 parts of quartz sand, 200 to 250 parts of water, 6.5 to 8 parts of water reduction agent, 0.8 to 1.2 parts of thickener, and 15 to 20 parts of polyvinyl alcohol fiber. The invention also provides a preparation method of the ultrahigh-toughness cement-based composite material. The ultrahigh-toughness cement-based composite material has the advantages that a large amount of fly ash and ore powder is utilized, and the industrial waste slag is consumed, so that the consumption of energy sources is effectively decreased, the pollution to environment is decreased, and the utilization rate of industrial waste slag is increased; the sources of raw materials are wide, and the ultrahigh-toughness cement-based composite material is conveniently popularized and applied to the engineering field of Chi
