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尾矿砂取代部分天然砂在混凝土中的应用很有必要。本文主要通过试验研究以一定比例的尾矿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。
Due to the current situation for the huge demands of the natural sand in the engineering construction,it is necessary to substitute the natural sand by the mine tailing sand in the application of concrete in the term of resources comprehensive application.This article will explain the comparison to the functions of operation & mechanics of the concretes which are studied and made by certain proportion of mixture with the natural sand instead of the mine tailing sand.
