摘　　要：工程实践证明，强度越高的混凝土抗冲磨性也相对好，C60～C80高强抗冲磨混凝土属于“以硬碰硬”的抗冲磨材料。只要采用低水胶比，掺加高性能减水剂，优先使用硅灰与矿渣粉或粉煤灰的复合超细掺合料，骨料最大粒径不超过20mm，精心施工，充分养护，着力从微观上提高、改善骨料与水泥石界面结构黏结强度和水泥石强度，就能轻易配制出C60-C80高强抗冲磨混凝土。The project practices proved that the higher-strength concrete has the better abrasion-erosion resistance.That kind of concrete is the ＂with shihroud＂ abrasion-erosion resistance material.So long as you adopt the low water to binder ratio,And give priority to the use of the compound superfine material of tabular spar and sand slag or fly ash cement.The largest grain size of aggregate should not exceed 20mm,build metic- ulously,protect sufficiently,put forth effort improving from microcosmic, improve the interface construction of aggregate and cement as well as the strength of stickiness and cement, you will make C60--C80 high-strength abrasion-erosion resistance concrete easily.
