High-strength water permeable brick and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a high-strength water permeable brick and a preparation method thereof. The water permeable brick comprises the following raw materials in parts by weight: 25-40 parts of cement, 10-20 parts of modified diatomite, 40-50 parts of fly ash, 60-80 parts of gravel, 3-5 parts of a water reducing agent and 5-10 parts of water, a preparation process of the modified diatomite comprises the following steps: (1) adding pretreated diatomite into a Tris-dopamine hydrochloride solution for stirring reaction, and obtaining polydopamine coated diatomite after the reaction is completed; (2) adding graphene into a solvent, then adding gamma-aminopropyltriethoxysilane, carrying out a heating reaction, and after the reaction is completed, carrying out purification to obtain silane modified graphene; and (3) adding the diatomite coated with the polydopamine and the silane modified graphene into absolute ethyl alcohol, stirring, and purifying to obtain the modified diatomite. The water permeable brick has excellent mechanical properties and wear resistance.
本发明属于建筑材料技术领域，具体涉及一种高强度透水砖及其制备方法。该透水砖包括以下重量份的原料：水泥25‑40份、改性硅藻土10‑20份、粉煤灰40‑50份、碎石60‑80份、减水剂3‑5份、水5‑10份；改性硅藻土的制备过程为：（1）将预处理后的硅藻土加入Tris‑多巴胺盐酸盐溶液中进行搅拌反应，反应完成后得到聚多巴胺包覆的硅藻土；（2）将石墨烯加入溶剂中，再加入γ‑氨丙基三乙氧基硅烷进行加热反应，反应完成后经纯化，得到硅烷改性石墨烯；（3）将聚多巴胺包覆的硅藻土、硅烷改性石墨烯加入无水乙醇中进行搅拌，经纯化，得到改性硅藻土。该透水砖具有优异的力学性能和耐磨性。
