  • Abstract:
  • Development of Self-Compacting Concrete (SCC) with Recycled Concrete Aggregates (RCA) from demolished and disposed wastes seems to be appropriate to problems like resource exhaustion and waste management. This project gives an overview of different techniques used for curing water in concrete. The purpose of this investigation was to conduct a test program on how much different curing conditions affect the strength of the concrete. In this work two SCC mixes were developed by Nan-Su’s method for target strengths of 40 and 60 MPa. Then the SCC mixtures were prepared by replacing Natural Aggregates with 25, 50, 75 and 100% of recycled coarse aggregates. The used water binder ratio for M40 is 0.35 and for M60 is 0.38. Super-plasticizers were also used to produce SCC. This study also considered the effect of different methods of curing on compressive strength of concrete. The cubes were cured using three methods (ponding, site curing, self-curing) and compressive strengths of 7 days and 28 days were determined. This project also makes us understand that the compressive strength that we will get at site curing is less than the standard curing method i.e., ponding. The usage of RCA is upto 25% replacement is seems to be good to get the targeted strength.
