摘要
The idea of recycling concrete waste as coarse aggregates for new concrete construction is gaining importance on the international scale. Although the mechanical properties of recycled aggregate concrete (RAC) are well known, the study on durability performances of RAC appears to be very limited. This study was an attempt to investigate and compare the durability performance of the RAC and natural aggregate concrete (NAC). The effect of addition of fly ash replacing cement partially on the overall performances of RAC and NAC was also incorporated. The test results reveal that the durability of RAC is comparatively less than that of NAC. However, the addition of fly ash replacing cement partially in RAC seems to enhance durability.
