Multi-solid-waste baking-free steaming-free water permeable brick with double-layer structure and preparation method thereof
The invention discloses a multi-solid-waste baking-free steaming-free water permeable brick with a double-layer structure and a preparation method thereof, and belongs to the field of preparation of building materials; the water permeable brick comprises a surface layer and a base layer, and the surface layer is composed of the raw materials in parts by weight: 80-100 parts of steel slag micro powder, 20-30 parts of silica fume, 1-4 parts of epoxy resin, 0.5-2 parts of a curing agent, 0.1-0.5 part of a water reducing agent and 10-20 parts of water; the base layer is composed of the raw materials in parts by weight: 10-20 parts of cement, 80-100 parts of iron ore waste rock, 20-30 parts of iron tailing powder, 0.1-0.5 part of a water reducing agent and 10-20 parts of water; the water permeable brick has the beneficial effects that the solid waste utilization rate is high, resource utilization of solid waste is achieved, the process is simple, high-temperature calcination is not needed,energy consumption is low, the surface layer adopts extremely fine particles, and the situation that the interior of the water permeable brick is blocked due to overlong use time is avoided; and silica fume is added into the surface layer as an excitant, so that the strength and the wear resistance of the water permeable brick are improved.
本发明公开了一种多固废免烧免蒸双层结构透水砖及其制备方法，属于建筑材料制备领域，所述透水砖包括面层和基层，面层原料组成按照重量分数计分别为：钢渣微粉80‑100份、硅灰20‑30份、环氧树脂1‑4份、固化剂0.5‑2份、减水剂0.1‑0.5份、水10‑20份；基层原料组成按照重量分数计分别为水泥10‑20份、铁矿废石80‑100份、铁尾矿粉20‑30份、减水剂0.1‑0.5份、水10‑20份，本发明的有益效果是固废利用率高，实现了固体废物的资源化利用，工艺简单，无需高温煅烧，能耗低，面层采用极细颗粒，避免因使用时间过长，透水砖内部被堵塞；面层中加入硅灰作为激发剂，提高透水砖的强度和抗磨损性能。
