Abstract
Construction and demolition waste represents both the largest waste stream as well as an increasingly utilized supply of material to the construction industry. On the other hand, it is now widely recognized and steadily accepted that there is a significant potential for reclaiming and recycling demolished debris for use in value-added applications to maximize environmental and possible economic benefits. Indeed, it is widely acknowledged that recycling of CDW for reuse as fine aggregate in new concrete production is technically viable and under certain circumstances environmentally sustainable and economically feasible route to convert this material in a valuable resource. To synthesis best performance Self Compacting Concrete (SCC), factors such as Super Plasticizer (SP), fly ash and fine recycled concrete aggregate (FRCA) are studied experimentally based on Taguchi analysis, keeping SCC efficiency as the response in MiniTab software. The fresh and hardened properties of SCC incorporating FRCA are investigated by the experimental study to evaluate the efficiency of SCC. Factors for optimum level were fixed by SN analysis using larger the better quality criteria. The analysis was evaluated for a confidence level of 95%. The most influencing factor and optimal level of factors for maximum efficiency are determined. Confirmation experiments were done for the optimal levels of factors and the predicted values were compared with the experimental values.
