Environment-friendly photocatalytic white ultra-high performance concrete and preparation method thereof
The invention discloses environment-friendly photocatalytic white ultra-high performance concrete and a preparation method thereof. The environment-friendly photocatalytic white ultra-high performance concrete is prepared from the following components in percentage by mass: 14-31 parts of white cement, 2.1-23 parts of limestone powder, 2-11 parts of white silica fume, 2-11 parts of metakaolin, 3-14.6 parts of steel fibers, 0.05-0.15 part of a polycarboxylate superplasticizer, 0.4-6.3 parts of nano TiO2, 33-50 parts of river sand, and the balance of water, wherein the water-binder ratio is 0.15-0.2. The compressive strength of the environment-friendly quartz mine tailing mud white ultra-high performance concrete is larger than or equal to 165 MPa, the breaking strength is larger than or equal to 35 MPa, the whiteness is larger than or equal to 67, the photocatalytic degradation rate is larger than or equal to 15%, and the concrete has good mechanical performance, decoration performance and photocatalytic performance. Meanwhile, dust-silica fume generated during ferrosilicon or silicon steel smelting and dust-limestone powder generated during limestone crushing are changed into wealth, resources are reasonably utilized, and the concrete has very important significance to the environmental protection cause.
本发明公开了一种环保光催化白色超高性能混凝土及其制备方法，各组分按照质量百分比为：白水泥14份‑31份、石灰石粉2.1‑23份、白硅灰2‑11份、偏高岭土2‑11份、钢纤维3‑14.6份、聚羧酸减水剂0.05‑0.15份、纳米TiO20.4‑6.3份，河沙33‑50份；余量为水，且水胶比为0.15‑0.2。本发明制造的环保型石英矿尾泥白色超高性能混凝土的抗压强度≥165Mpa，抗折强度≥35MPa,白度≥67，光催化降解率≥15％，具有较好的力学性能、装饰性能和光催化性能。同时采用来自冶炼硅铁或硅钢时产生的粉尘‑硅灰、采用破碎石灰石产生的的粉尘‑石灰石粉变废为宝，合理利用资源，对环保事业具有非常重要的意义。
