Photocatalytic foam concrete and preparation method thereof
The invention belongs to the technical field of building materials, and discloses photocatalytic foam concrete and a preparation method thereof. The photocatalytic foam concrete is prepared from the following raw materials in percentage by mass: 3.2 to 12.8 percent of photocatalytic foam, 62.0 to 68.9 percent of white cement, 0.2 to 0.6 percent of polycarboxylate superplasticizer and 24.6 to 27.5 percent of water, and the photocatalytic foam is prepared from nano TiO2, a dispersion stabilizer, a foaming agent and water. The nano TiO2 is loaded on the foam to form the stable photocatalytic foam, then the photocatalytic foam is used for preparing the photocatalytic foam concrete, the obtained photocatalytic foam concrete has a stable porous structure, the nano TiO2 is fully attached to the pore wall of the concrete, the exposure under ultraviolet rays and the contact amount with pollutants are obviously increased, and the photocatalytic foam concrete has a good photocatalytic effect. The utilization rate of the nano TiO2 is improved, and the nano TiO2 has excellent photocatalytic performance.
本发明属于建筑材料技术领域，公开了一种光催化泡沫混凝土及其制备方法。所述光催化泡沫混凝土，由以下质量百分含量的原料组成：光催化泡沫3.2‑12.8％、白水泥62.0‑68.9％、聚羧酸减水剂0.2‑0.6％、水24.6‑27.5％，其中，光催化泡沫由纳米TiO2、分散稳定剂、发泡剂和水组成。本发明先将纳米TiO2负载于泡沫上形成稳定的光催化泡沫，再将光催化泡沫用于制备光催化泡沫混凝土，得到的光催化泡沫混凝土具有稳定的多孔结构，纳米TiO2充分附着于混凝土孔壁上，在紫外线下的暴露量和与污染物的接触量明显增多，提高了纳米TiO2的利用率，具有优异的光催化性能。
