摘　　要：介绍了人工砂混凝土的研究和工程应用情况,说明采用人工砂替代天然砂,可以提高混凝土强度和耐久性,从而可用于各种强度级别的混凝土工程,并认为人工砂是混凝土配制中一种理想的细骨料。The state of research and engineering application of concrete made with artificial sand is described. And it shows that, by using artificial sand instead of natural sand, the strength and some durability of concrete will be inhanced, so that it can be used in many engineering with requirements of different strength grade. Therefore, the artificial sand is an ideal material for preparing concrete.

关 键 词：人工砂 高强混凝土 预应力高强混凝土管桩 天然砂
