It has become vital to look for alternatives to the non-renewable natural resources utilized in the building industry due to the vast and quick expansion in that sector in order to safeguard such resources from waste. Recycling varied concrete debris from demolished concrete buildings to substitute natural gravel in the production of various concrete mix types is one way to do this. In this study, the physico-mechanical characteristics of steel fiber-reinforced self-compacting concrete made of quartz gravel were examined. The percentages of recycled gravel used to replace the quartz gravel were 25, 50, and 75%, respectively. According to the findings, up to 75% of the quartz gravel may be replaced with recycled gravel. The correlation between the concrete's ultrasonic speed and mechanical strength was strong and promising.

Abstract


It has become vital to look for alternatives to the non-renewable natural resources utilized in the building industry due to the vast and quick expansion in that sector in order to safeguard such resources from waste. Recycling varied concrete debris from demolished concrete buildings to substitute natural gravel in the production of various concrete mix types is one way to do this. In this study, the physico-mechanical characteristics of steel fiber-reinforced self-compacting concrete made of quartz gravel were examined. The percentages of recycled gravel used to replace the quartz gravel were 25, 50, and 75%, respectively. According to the findings, up to 75% of the quartz gravel may be replaced with recycled gravel. The correlation between the concrete's ultrasonic speed and mechanical strength was strong and promising.
