摘要
针对当前工程建设对天然砂大量需求的状况,从资源综合利用的角度研究以人工砂取代部分天然砂在混凝土中的应用很有必要。通过试验,以一定比例的人工砂代替天然砂制作混凝土,并将其工作性能、力学性能与天然砂混凝土进行比较。结果表明,在20%～30%比例替代率的条件下,混合砂混凝土的各种性能优良,可以满足施工要求,用于预拌混凝土的生产。
According to the current state of sand resources, Try to replace part of the natural sand by artificial sand in the concrete application is necessary. Experimental Study of mixed sand through the work of concrete, mechanical properties and compare to natural sand, it can be concluded： Mixed sand concrete has excellent performance, can fully meet the construction requirements and also can be used for the production of pre-mixed concrete.
