Abstract
The objective of present investigation is to develop stress – block parameters for the design of reinforced recycled aggregate concrete members. To arrive at the objectives, a comprehensive experimental programme was undertaken. The influence of replacement ratio, (Rr) the ratio of recycled coarse aggregate to total coarse aggregate (Rr = RCA/TCA) on properties of recycled aggregate concrete was studied. The scope of the investigation programme is defined to generate stress strain test data of concrete, viz; M15, M20, M25, M30, and M35 and five replacement ratios, viz; 0, 0.5, 0.75, 0.85, and 1.0 were considered. A total of 150 cylinder specimens’ and 48 RC beam specimens were cast for the stress- strain characteristics and flexural design of hardened concrete and design parameters are developed for recycled aggregate concrete.
