摘要
研究了公路碾压混凝土的物理、力学等性能,并与常态混凝土进行了对比。结果表明,在水胶比相同时,碾压混凝土的胶凝材料用量比常态混凝土少10%左右,但其强度却可提高约10%;碾压混凝土的抗冻性能优于常态混凝土;干缩率比常态混凝土小。
This paper discusses the performance of roller compacted concrete pavement ( RCCP)andcontrasts it to normal concrete.Results show that at the same ratio of water to cementitious materials,roller compacted concrete(RCC) uses about 10% less cemented materials than normal concrete does,while its strength goes up about 10%。 Resistance to freezing of RCCis superior to that of convertionalconcrete and the shrinkage ratio of the former is smaller than that of the latter.
