The invention discloses an ultrahigh-toughness cement-based composite material, which is prepared from the following raw materials in percentage by weight: 40-50% of cement, 30-40%of sand, 5%of glass fiber, 2%of polymer, 10-12%of water, 2%of a curing agent, 2%of a defoaming agent, 5%of rubber powder, 5%of silica gel powder, 2%of a toughening agent, 4%of magnesium oxide and 3%of a sodium carbonate solution. According to the invention, rubber powder and silica gel powder are mixed into cement, the toughness of the material is improved by utilizing the ultrahigh toughness of the rubber powder and the silica gel powder, the viscosity of the cement is increased by adding the magnesium oxide and the sodium carbonate solution, and by increasing the viscosity and the toughness of the cement, it can be ensured that the cement-based composite material can bear large compression deformation when being vibrated and pressed to keep the whole, the material is prevented from being broken, the anti-seismic effect of the material is improved, the same strength can be guaranteed after the material is cracked, the shear resistance of the material has the obvious ductility characteristic under the shear load effect, and a stress-strain curve has obvious strain hardening characteristics.
本发明公开了一种超高韧性水泥基复合材料，原料配比如下：水泥40％‑50％、砂30‑40％、玻璃纤维5％、聚合物2％、水10％‑12％、固化剂2％、消泡剂2％、橡胶粉5％、硅胶粉5％、增韧剂2％、氧镁4％与纯碱溶液3％；本发明专利通过在水泥中混入橡胶粉和硅胶粉，利用橡胶粉和硅胶粉自带的超高韧性，提升材料的韧性，通过加入氧镁和纯碱溶液，来增加水泥的粘性，通过增加水泥的粘性和韧性，保证水泥基复合材料在受到振动和压力时可承受较大的压缩变形而保持整体，避免材料发生断裂，提高材料的抗震效果，且材料在开裂后也可保证相同强度，其的抗剪性能在剪切荷载作用下有明显的延性特征，应力应变曲线有明显的应变硬化特征。
