Abstract: It is clear that adding the emery into the cement concrete could improve the cement concretes abrasion resistance. However, if can emery improve mechanical performance of the cement concrete is a question need to research. This research analyze the emerys effect to the mechanical performance of cement concrete by large number of experiments and give the type of emery and quantity for different cement concrete to get the emery cement concrete that have fine mechanical performance to meet need

Key words: cement concrete, emery, mixture ratio, mechanical performance, abrasion resistance

摘要： 在水泥砼中掺入金刚砂能提高水泥砼的耐磨性能，是很明显的事实，然而在提高砼耐磨性能的同时，能否 保证砼的力学性能指标，是一个值得探讨的课题。笔者通过大量的室内试验，分析了金刚砂对水泥砼的力学性能和 耐磨性能的影响，提出了掺混合材料水泥砼金刚砂的合理类型和掺量，目的是为了配置出具有较好耐磨性能和力 学性能的金刚砂水泥砼，满足公路工程需要。
