The invention provides liquid-fiber-toughened cement paste. The liquid-fiber-toughened cement paste is prepared from, by mass, 100 parts of cement, 35-60 parts of water, 2.5-23.5 parts of self-sealingelastic material, 0.5-3 parts of dispersing agent, 2-5 parts of filtrate reducer, 0.5-2 parts of reinforcing agent, 0.5-2 parts of expanding agent, 0.5-3 parts of retarder and 1-7 parts of liquid fibers. According to the liquid-fiber-toughened cement paste, the liquid fibers serve as reinforcing and toughening components, and through interaction of the liquid fibers and other components, the strength and the impact resistance of the liquid-fiber-toughened cement paste are improved. Experimental results show that the compressive strength of set cement prepared through the liquid-fiber-toughened cement paste can be 22.6 MPa, the breaking strength can be 4.40 MPa, the elastic modulus can be 4.10 GPa, and the impact resistance can be 2.84 KJ/m<2>.
