| Abstract: | Development of Self Compacting Concrete (SCC) with recycled concrete aggregates (RCA) from demolished and disposed wastes seems a logically viable answers to problems like resource exhaustion and waste management. In this work, three SCC mixes were developed by modification of Nan-Su's method for target strengths of 30, 50 and 70 MPa. Flowability of concrete was ensured to conform to EFNARC specifications through various fresh property tests. Compressive strength tests were conducted to include assessment of variation in curing period for durations of 28, 56 and 90days. Durability properties like resistance to H2SO4, capillary water sorption effects of use of RCA were studied. Observations indicated that better results will be obtained if processed RCA are used. RCA concrete couldn't attain compressive strength as that of Natural aggregate (NCA) concrete and also the effect of acid and capillary water sorption were amplified in case of greater replacements of RCA. |
