The result shows that the abrasion resistance capability of the aggregate is a little degradation, and that the coarse aggregate coated by powder has a little effects on the mechanic properties of RCC, such as the compressive strength and limiting tensile

结果表明：粗骨料抗磨耗能力略差，粗骨料表面裹粉对碾压混凝土的抗压强度、极限拉伸值及引气剂的引气效果影响较小，对碾压混凝土抗渗、抗冻性能影响不大。
