摘　　要：耐磨性是道路和桥梁混凝土的主要性能之一,提高混凝土的耐磨性能对保证其耐久性有重要意义.笔者基于灰熵法,分析了影响粉煤灰砼耐磨性因素的显著性,分析结果表明用水量和集料影响显著,水泥用量次之,粉煤灰掺量影响最小,可以为有耐磨要求的粉煤灰混凝土设计提供科学依据.灰熵法理论推导较为严密,计算简便,灰熵关联度大小不受分辨系数的影响,能克服一般灰关联方法存在的不足,在分析各影响因素的显著性时可以取得更为理想的结果.Wear resistance is one of the main properties of road and bridge concrete. Improving the wear resistance of concrete plays an important part in ensuring its durability. Based on the gray entropy theory, This paper analysed the significance of wearable corrosion of fly-ash concrete . The results showed that water and aggregate play a major role in wearable corrosion,followed by cement consumption, fly ash content has the least impact. The deduction of gray entropy theory is very strict, and the calculation is simple. The grey relation entropy method can overcome the disadvantage of normal grey relation method, and the relation degree of grey entropy were not influenced by discriminant factor. Better results can be achieved for the use of gray entropy theory when analysing of the effects of different factors.
