铁尾矿用于混凝土生产的试验及发展设想

The Try and Developmental Ideas That Iron Tailings Used for Concrete

指出了当前天然砂的短缺和开发利用铁尾矿的重要意义;列举了我国铁尾矿用于混凝土的实例;介绍了将马钢南山铁矿的铁尾矿用于C60级混凝土的实验研究成果。对掺有铁尾矿混凝土有关性能的影响因素作了分析,对试验研究所采用的尾矿砂通过检测部门进行检测,检测结果表明,各项指标均合格。同时提出了将铁尾矿用于混凝土生产和其他新型建筑材料的发展设想。

This paper points out the significance of developing Iron tailings to recycling and shortage of naturalsand. Main instance of iron tailings used for concrete are listed is listed in our country. The experimental research results of the iron tailings of Ma steel Nanshan iron ore used for concrete of C60 grade is introduced, analysis relating to factors affecting in performance of concrete that mixed with iron tailings is done, testing the tailing sand for experimental study did test particularly and test results make clear the various elementsare all up to standard go through the authorities, meanwhile pointing out that this test does not once and for all. This paper proposes developmental ideas of using iron tailings for concrete and new building materials that.
