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.
本发明公开了一种自清洁水泥基复合材料及生产方法，包括以下步骤：将含18～38％wt无机玄武岩纤维，玻璃纤维，陶瓷纤维的芳纶，纤维，芳纶纤维，光催化材料，尼龙纤维，维尼纶纤维和输入纤维成捻机编织成64支的纤维线，将得到的纤维线输入纤维布编织机织成网格为1m×1m、幅宽为2.00m的网状纤维布；新拌混凝土的养护过程可吸入大量的CO2，使水泥熟料中的硅酸钙及少量水化产物与CO2反应生成碳酸钙和硅胶，能获得较高的早期强度,大大缩短混凝土养护时间,有较好的尺寸稳定性及其他性能，引入尾矿作为改性组分也是减排的过程，纳米改性的混凝土组分可持续吸收大气中的二氧化碳，同时能提升建筑材料的整体力学性能和耐久性。
