摘要
碾压混凝土与常态混凝土耐久性对比试验证实，碾压混凝土具有较常规混凝土更好的耐久性。其耐久性更好的主要原因是水泥水化产生的氢氧化钙与粉煤灰二次反应生成新的结石和凝胶体充填孔隙，使碾压混凝土更致密，具有更稳定的内部结构。
The compallson test of the roller compacted concrete and the normal concrete proved that the durability o f the roller compacted concrete is higher than that of the normal concrete due to its voids being filled by new cemented particles and gel produced from secondary reaction of calcium hydroxide and flyash caused by cement hydration heat, which makes the roller compacted concrete more compact and its internal stmcture more stable.
