| 摘 要： | 与常规骨料混凝土相比，再生骨料混凝土因骨料的结合状况而导致了其自身强度的降低。添加适量粉煤灰的再生骨料混凝土在整体性能有了实质提高。最后将常规混凝土（不含粉煤灰）和再生骨料混凝土（含10％粉煤灰）的耐久性能进行了对比研究。评估耐久性考虑的参数有：干缩力，吸水率，透水性，抗酸性及抗硫酸盐侵蚀性。结果表明，添加的10％粉煤灰也提高了再生骨料混凝土的耐久性能，并且也为再生骨料代替常规骨料的可行性提供了有力支撑。

| Abstract: | The incorporation of recycled concrete aggregate generally decreases the strength of recycled aggregate concrete(RAC) as compared to that of similar conventional aggregate concrete.With the optimum addition of fly ash replacing cement(10% for the present mixture in the study),the overall behaviour of RAC can be improved substantially.Finally,a comparison on durability properties of conventional and recycled aggregate concrete without / with 10% fly ash addition has been made.The parameters considered to eva... |
