The invention belongs to the technical field of engineering materials, and in particular relates to a high-strength and high-tough fiber woven mesh reinforced nano-cement-based composite material and a preparation method thereof, comprising the following steps: (1) after dissolving the dispersion, adding nano-materials, stirring, and ultrasonicating, Obtaining nanomaterial dispersion; (2) mixing water and nanomaterial dispersion, and stirring; (3) adding cement mortar, stirring, and entering a mold, and vibrating at high frequency on a vibrating table; (4) weaving the prepared fibers The net is placed in the formwork, the concrete slurry prepared in step (3) is poured, and after hardening, it is demolded for curing. The invention reduces the interface porosity, improves the bonding ability of the fiber woven net and the matrix, improves the utilization rate of the fiber net in the reinforced concrete of the ordinary fiber woven net, improves the tensile performance under the guarantee of compression resistance and bending resistance, and improves the Further improving the seismic performance of the structure is of great significance and practical benefit to my country's scientific and technological innovation, economic development, natural environment and social progress. |
