Durability Studies on High Strength Recycled Aggregate Concrete
The idea of recycling concrete waste as coarse aggregates for new concrete construction is gaining importance on the international scale but the studies on durability performance of Recycled Aggregate Concrete (RAC) are limited. There is a little or no work carried out on high strength recycled aggregate concrete. This study was an attempt to investigate and compare the acid resistance of the RAC and Natural Aggregate Concrete (NAC) of grade M50. In the present experimental investigation, concrete specimens of 0% and 50% RAC were prepared, cured and immersed in H2SO4 solution at 3% concentration at 7 and 28 days respectively. The period of exposure was varied from 3 days to 56 days. The loss of weight, compressive and tensile strengths of the specimens were found to be higher when RAC is exposed to acidic environment compared to NAC.
