Fiber-enhanced cement-based composite material
The invention aims at providing a fiber-enhanced cement-based composite material. The material comprises the raw materials of, by weight, 120-160 parts of cement, 150-200 parts of a fine aggregate, 230-330 parts of a coarse aggregate, 26-40 parts of silica fume, 10-20 parts of volcanic ash, 23-35 parts of fly ash, 12-25 parts of carbon nanotube, 10-23 parts of polymer resin, 5-12 parts of a water reducing agent, 35-55 parts of water, and 5-20 parts of fiber. According to the invention, a water-binder ratio is controlled at below 0.23; materials with specific types, specific particle sizes and specific amounts are selected; and several excellent fiber materials and polymer resin are selected, such that the composite material is more compact. On a basis that the strength of the composite material meets application requirements, the material has certain toughness. The fracture energy can reach 20000-40000J/m<2>, and interfacial bond strength is high. The material can be subjected to natural curing or high-temperature steam curing, such that construction processes such as model casting, spraying and scrape coating can be satisfied.
