Abstract

The invention discloses a self-cleaning cement-based composite material and a production method thereof, and the production method comprises the following steps: aramid fibers containing 18-38% wt of inorganic basalt fibers, glass fibers and ceramic fibers, fibers, aramid fibers, a photocatalytic material, nylon fibers, vinylon fibers are input in a fiber twisting machine for being knitted to 64 fiber threads; the obtained fiber lines can be input into a fiber cloth knitting machine to be knitted into net-shaped fiber cloth with the mesh being 1 m*1 m and the breadth being 2.00 m; a large amount of CO2 can be sucked in the curing process of fresh concrete, calcium silicate and a small amount of hydration products in cement clinker react with CO2 to generate calcium carbonate and silica gel, high early strength can be obtained, the concrete curing time is greatly shortened, good size stability and other performance are achieved, the process of emission reduction is achieved by introducing tailings as a modifying component, the nano-modified concrete component can continuously absorb carbon dioxide in the atmosphere, and meanwhile, the overall mechanical property and durability of the building material can be improved.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a self-cleaning cement-based composite material and a production method. Background technique [0002] Cement concrete: refers to the collective name of engineering composite materials that are made of cement, sand, stone, etc. mixed with water. The term concrete usually refers to cement as cementing material, sand and stone as aggregate; mixed with water (with or without admixtures and admixtures) in a certain proportion, obtained by stirring, molding and curing Cement concrete, also known as ordinary concrete, is widely used in civil engineering. Cement concrete products refer to various building components and engineering prefabricated parts processed from cement concrete, which are customarily called cement products, including cement concrete slabs, blocks, beams, columns, pipes and other geometric shapes. [0003] Concrete prefabricated blocks need to be cured du...
