Macro-level Performance Assessment of Concrete: Experimental Fracture Analysis

Abstract

Natural coarse aggregate (NCA) can potentially be replaced with recycled coarse aggregate (RCA), which is derived from the leftover concrete from construction and demolition (C &D) projects. However, RCA has drawbacks of its own, notably because of the porous mortar layer and micro-cracks. This motivates academics throughout the world to reduce the impact of the RCA’s inherent drawbacks in recycled aggregate concrete (RAC). Different mix design techniques, mixing procedures, the addition of fibres, and the addition of mineral admixtures are suggested in this context.
