Application of Copper Slag in Ultra-high Performance Concrete
Ultra-High Performance Concrete (UHPC) was hindered by the use of non-renewable quartz sand, so there was a need to find a new sustainable material to replace quartz sand. This study investigates the possibility of using copper slag as an aggregate instead of quartz sand to make sustainable UHPC. To ensure the workability and good …
