摘要
试验研究了添加膨胀组分的复合矿物掺合料的混凝土耐磨性能。设计了20个配合比的试验来评价混凝土的性能，研究发现，在掺合料取代率为40％时混凝土具有较高的耐磨性。对于矿粉-膨胀组分复合型掺合料，膨胀剂占掺合料比例8％～12％时，混凝土耐磨性能随膨胀剂掺量的增加而增大。
In this experiment, the abrasion resistance of concrete mixed with expansive compound mineral admixture is studied. Based on a contrastive concrete experiment of 20 mix proportions, it is concluded that the concrete mixed with 40% mineral admixture has the largest abrasion resistance. In addition, if the expansive agent in compound admixture of ground slag and expansive component ranges from 8% to 12%, the abrasion resistance of concrete increases with expansive agent..
