Evaluation of various treatment methods for enhancing the physical and morphological properties of coarse recycled concrete aggregate

The main objective of this research is to enhance the physical and morphological properties of coarse recycled concrete aggregate (CRCA) by combining different types of treatment methods. Heat treatments included various temperatures (250°C, 350°C, 500°C and 750°C). Presoaking method involved the use of strong acid HCl and weak acid C2H4O2, whereas short mechanical treatment included the utilization of a Micro-Deval device. In order to …
