摘　　要：钼尾矿作为全球开采钼矿产资源产生的固体废弃物之一,将其替代混凝土细骨料或水泥既可解决环境污染,还可弥补天然砂资源短缺的现状,是钼尾矿最经济、最环保的资源化利用方式之一,符合绿色可持续发展的战略要求。本文综述了钼尾矿在混凝土中应用的研究进展,分析了钼尾矿的理化特性,探讨了钼尾矿混凝土的工作性能、力学性能及耐久性能,提出了钼尾矿在混凝土应用中现存的主要问题。以期为实现钼尾矿在混凝土中的广泛应用打下基础。Molybdenum tailings, as one of the solid wastes which are produced by the exploitation of molybdenum mineral resources in the world, can not only solve the environmental pollution, but also make up for the shortage of natural sand resources by replacing concrete fine aggregate or cement with molybdenum tailings. It is one of the most economically and environmentally friendly resource utilization method of molybdenum tailings, due to it can able to meet the strategic requirements of green and sustainable development. In this paper, the research progress of application of molybdenum tailings in concrete is summarized. Firstly, the physical and chemical properties of molybdenum tailings are analyzed,and secondly, the working performance, mechanical performance and durability performance of molybdenum tailings concrete are discussed, finally the main problems existing in application of molybdenum tailings in concrete are suggested. This work is expected to be useful for the wide application of molybdenum tailings in concrete.
