Experimental Investigation of Self Compacting Concrete Using Recycled Demolished Waste Aggregate as Coarse Aggregates Along with Steel Fibres
摘要
Demolition waste generated in construction work and its management is still a serious challenge for construction industry. The promising way to solve this problem is recycling of demolished waste and used it as a construction material. Therefore, the objective of present research work is also oriented towards the utilization of recycled demolished waste aggregate (rDWAs) in self-compacting concrete (SCC). In this study attempt was made to evaluate the impact of substitution of natural coarse aggregates (NAs) with recycled demolished waste aggregate along with steel fibres on mechanical properties and durability properties of self-compacting concrete. Optimization techniques were used to design the experiments. Central composite design (CCD) in addition with response surface methodology (RSM) is used for optimization. Optimized conditions for various properties were shown in results obtained from central composite design. The results of this study revealed that rDWAs can be replaced NAs in self compacting concrete and help in management of solid waste.
