尾矿制备建筑材料的研究进展

Progress of Research on Building Materials Prepared from Tailings

尾矿是矿石加工及利用过程中产生的有价元素含量较低的部分。大量尾矿的堆存既浪费土地,又危害环境。将尾矿资源化利用是当今社会节能环保、提高经济效益的有效途径。利用尾矿制备建筑材料是近年来尾矿资源化利用的重要发展方向。国内外就尾矿在建筑材料方面的开发做了大量研究。研究表明,尾矿可用于制备混凝土、水泥、建筑用砖和陶瓷等。本文综述了尾矿在建筑材料方面的研究进展,以期为尾矿在建筑材料领域的利用提供参考。

Tailings are the lower content of valuable elements produced during the processing and utilization of ore.The accumulation of a large amount of tailings wastes land and harms the environment.Utilizing tailings as a resource is an effective way to save energy,protect the environment,and improve economic benefits in today’s society.The use of tailings to prepare building materials is an important development direction in the utilization of tailings in recent years.A lot of research has been done at home and abroad on the development of tailings in building materials.Studies have shown that tailings can be used to prepare concrete,cement,building bricks and ceramics.This paper reviews the research progress of tailings in building materials,in order to provide a reference for the use of tailings in the field of building materials.
