Mildew-proof building material based on recycled concrete
The invention belongs to the technical field of building materials, and particularly relates to a mildew-proof building material based on recycled concrete. The mildew-proof building material based on the recycled concrete is specifically prepared from 20 to 22 parts of concrete, 12 to 15 parts of fly ash, 8 to 10 parts of silica powder, 7 to 9 parts of kaolin, 7 to 11 parts of diatom ooze, 3 to 4 parts of sodium nitrite, 2 to 5 parts of magnesium chloride, 3 to 6 parts of polyvinyl chloride, 2 to 4 parts of dimethyl fumarate, 3 to 5 parts of polyurethane, 1 to 1.5 parts of zirconium dioxide, 2 to 2.5 parts of white bamboo charcoal powder, 0.8 to 1.2 parts of titanium dioxide and 1.3 to 1.5 parts of foaming agent. According to the mildew-proof building material, zirconium dioxide, white bamboo charcoal powder and titanium dioxide are added in the production and preparation process of the mildew-proof building material, and concrete is used as a production basis, so that moisture in humid air can be effectively prevented from being absorbed, the building material is prevented from mildewing after being used for a long time, and the mildew-proof building material has the advantages of being safe and reliable. And the body health of residents is prevented from being influenced.
本发明属于建筑材料技术领域，具体为一种基于再生混凝土的防霉建筑材料，该基于再生混凝土的防霉建筑材料具体包括：混凝土20‑22份、粉煤灰12‑15份、硅石粉8‑10份、高岭土7‑9份、硅藻泥7‑11份、亚硝酸钠3‑4份、氯化镁2‑5份、聚氯乙烯3‑6份、富马酸二甲酯2‑4份、聚氨酯3‑5份、二氧化锆1‑1.5份、白竹炭粉2‑2.5份、钛白粉0.8‑1.2份、发泡剂1.3‑1.5份、活性剂0.8‑1.5份、纤维素2‑3份、减水剂3‑3.5份、抗氧化剂0.2‑0.5份和水，该防霉建筑材料在生产制备的过程中，添加了二氧化锆、白竹炭粉和钛白粉，且通过以混凝土为生产基础，可以有效避免吸收潮湿空气中的水分，防止建筑材料在长时间使用后发生霉变，避免影响居住人群的身体健康。
