摘　　要：本文研究矿山废石与天然砂石混合使用对混凝土工作性能、力学性能和耐久性的影响。试验结果表明，对于中低强度混凝土，只要合理利用矿山废石，其混凝土工作性能、抗压强度和耐久性能均能达到要求，甚至一些性能还高于天然砂石混凝土；矿山废石对于高强度等级混凝土的强度略有影响，但是谨慎使用同样可以无特殊要求的混凝土。This paper studies chats and natural sand and gravel mixed using effect on the working performance, mechanical property and durability of concrete. The results show that for middle and lower strength concrete, as long as reasonable use chats, the concrete working performance, compressive strength and endurance performance all can meet the requirements, even some performance is higher than the natural aggregate concrete. Chats has certain effect for the strength of high strength concrete, but only careful using, it also can he used in no special required concrete.
