Abstract

A compacted concrete waste composite material (CWC) is developed using a cold compaction approach with recycled concrete waste particles, without the use of cement. This study aims to investigate the effects of carbonation and the original quality of the concrete waste (CW) particles on the properties of composite material, with the goal of proposing a pretreatment of concrete waste particles which proposed for CO2 sequestered for producing CWC with attained strength. This study found that the original quality of the CW strongly affects the properties of the CWC.

Cold-Compacted Concrete Waste Composites – Sustainable Low-Carbon Materials: Effect of Original Concrete Quality

A compacted concrete waste composite material (CWC) is developed using a cold compaction approach with recycled concrete waste particles, without the use of cement. This study aims to investigate the effects of carbonation and the original quality of the concrete waste (CW) particles on the properties of composite material, with the goal of proposing a pretreatment of concrete waste particles which proposed for CO2 sequestered for producing CWC with attained strength. This study found that the original quality of the CW strongly affects the properties of the CWC.
