摘要
针对经济快速发展所带来的胶凝材料和河砂等资源短缺问题,研究磷尾矿作为胶凝材料和细骨料对混凝土的影响。结果表明:当掺入5%的磷尾矿粉作为胶凝材料替代水泥时混凝土的力学性能的改善效果最好,当掺入40%的磷尾矿矿砂作为细骨料替代河砂时混凝土的力学性能提高最明显,作为固体废弃物的磷尾矿可以加入到混凝土中使用。
In view of the shortage of cementing materials and river sand caused by rapid economic development,the effects of phosphorus tailings as cementing materials and fine aggregates on concrete were studied by experiments.The results show that the addition of 5%phosphorous tailing powder has the best effect as a substitute for cement.The addition of 40%phosphorus tail ore as fine aggregate to replace river sand has the best effect,and its mechanical properties have the most obvious improve-ment.It can be seen that phosphorus tailings can be added to concrete as a solid waste.
