Research Progress on Application of Molybdenum Tailings in Concrete

Abstract

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.
