Manganese tailing water permeable brick and preparation method thereof
The invention discloses a manganese tailing water permeable brick and a preparation method thereof. The manganese tailing water permeable brick comprises a base layer and a facing layer, and a base layer blank comprises the following raw materials in parts by mass: 40-60 parts of manganese tailings, 10-15 parts of cement, 15-20 parts of water and 0.135-0.38 part of a pore forming agent; the facinglayer blank is prepared from the following raw materials in parts by mass: 35 to 50 parts of manganese tailings, 10 to 15 parts of cement, 15 to 20 parts of water and 0.12 to 0.34 part of pore forming agent. The components such as SiO2 and Al2O3 in the tailings have potential gelling activity; under the action of cement, the gelling property can be exerted and the basic conditions for making bricks can be met; manganese ore is used as a main raw material, a small amount of cement is used as a cementing material, a pore-forming agent is added for uniform mixing and stirring, the water permeable brick is prepared through compression molding and maintenance, the raw materials are easy to obtain, the preparation process is simple, a high-temperature sintering process is avoided, energy consumption is greatly reduced, meanwhile, the raw material cost is reduced, and industrialization is facilitated.
本发明的一种锰尾矿透水砖及其制备方法。本发明的一种锰尾矿透水砖，包括基层和饰面层，其中，基层坯料包括如下质量份数的原料：锰尾矿40‑60份，水泥10‑15份，水15‑20份，造孔剂0.135‑0.38份；饰面层坯料包括如下质量份数的原料：锰尾矿35‑50份，水泥10‑15份，水15‑20份，造孔剂0.12‑0.34份。本发明的尾矿中的SiO及AlO等成分具有潜在的胶凝活性，在水泥的作用下，能发挥其胶凝特性，满足制砖的基本条件，以锰矿为主要原料，再辅以少量水泥作为胶凝材料，配以造孔剂混合搅拌均匀，通过压制成型、养护制得透水砖，原料易得、制备工艺简单，既避免了高温烧结工艺，大大降低了能耗，同时又降低了原料成本，有利于产业化。
