Graphite tailing high-performance cement mortar and preparation method thereof
The invention discloses graphite tailing high-performance cement mortar and a preparation method thereof, and belongs to the technical field of concrete. In order to solve the recycling problem of solid waste graphite tailings and fly ash and relieve the condition of tension of supply and demand of gravel, the method comprises the following steps: adding a part of a water reducing agent into a half of weighed water, dissolving, adding a multi-walled carbon nanotube, stirring, and carrying out ultrasonic treatment to obtain a first mixture; uniformly mixing the sand and the graphite tailings in the mixing stirrer to obtain a second mixture; adding the first mixture, the cement, the residual water reducing agent and the residual half mass of water into a stirring pot, and stirring to obtain a third mixture; and adding the second mixture into the third mixture, continuously stirring in the stirring pot, and stirring at a high speed for a certain time to obtain the graphite tailing high-performance cement mortar. According to the invention, the solid wastes are applied to the building mortar to partially replace cement and sand, so that the building cost is reduced, and meanwhile, the environmental problem caused by accumulation of the solid wastes is also alleviated.
一种石墨尾矿高性能水泥砂浆及其制备方法，属于混凝土技术领域。为解决固体废物石墨尾矿、粉煤灰的回收再利用问题、缓解砂石供需紧张情况，本发明将称量好的一半质量的水，加入一部分减水剂，溶解后再加入多壁碳纳米管，搅拌后超声后得到第一混合物；将砂子和石墨尾矿在混合搅拌机中混合均匀后，得到第二混合物；将第一混合物、水泥、剩余的减水剂、剩余的一半质量的水加入到搅拌锅中搅拌得到第三混合物；将第二混合物加入到第三混合物中，在搅拌锅中继续搅拌，高速搅拌一定时间后，得到石墨尾矿高性能水泥砂浆。本发明将固体废弃物应用于建筑砂浆中，部分替代水泥和替代砂子，降低建筑成本，同时也减轻固体废弃物的堆积带来的环境问题。
