Graphite tailing fine aggregate cement-based superfine powder mortar
The invention provides graphite tailing fine aggregate cement-based superfine powder mortar. The graphite tailing fine aggregate cement-based superfine powder mortar is prepared from fine aggregate, a cementing material, water and a water reducing agent, the fine aggregate is composed of graphite tailings, sand and diatomite; the cementing material is composed of cement and fly ash; the concrete is prepared from the following raw materials in parts by weight: 5-28 parts of graphite tailings, 37-63 parts of sand, 1-3 parts of diatomite, 15-25 parts of cement, 2-8 parts of fly ash, 8-11 parts of water and 0.13-0.17 part of a water reducing agent. The graphite tailings are calcined and activated graphite tailings, and the calcining temperature is 750 DEG C; the diatomite is calcined and activated diatomite, and the calcining temperature is 800 DEG C. The prepared mortar is optimized in pore structure, high in mechanical strength and high in compactness, the mortar performance is improved, a theoretical basis is provided for application of the graphite tailings in the aspect of building materials, and technical support is provided for solving the problems of large accumulation amount of the graphite tailings, environmental pollution and the like of enterprises.
本发明提供一种石墨尾矿细集料水泥基超细粉体砂浆，由细集料、胶凝材料、水和减水剂为原料制备而成；细集料组成为：石墨尾矿、砂子和硅藻土；胶凝材料组成为：水泥和粉煤灰；以上各原料重量份数分别为：石墨尾矿5～28份、砂子37～63份、硅藻土1～3份、水泥15～25份、粉煤灰2～8份、水8～11份、减水剂0.13～0.17份；石墨尾矿为经过煅烧活化的石墨尾矿，煅烧温度为750℃；硅藻土为经过煅烧活化的硅藻土，煅烧温度为800℃。本发明制备的砂浆孔隙结构得到优化，力学强度高，密实性强，提升了砂浆性能，为石墨尾矿在建筑材料方面的应用提供理论基础，为解决企业石墨尾矿堆积量大、环境污染等问题提供技术支持。
