WebbA large amount of granite sludge waste (GSW) is produced during the granite quarry processing that has a negative impact on the environment. The main aim of this study to investigate the possibility of partial replacement of brick clay by GSW and silica fume (SF) due to the similarity of the mineralogical composition of GSW and clay. Webbsludge waste rate has been developed. It uses proportional-integral derivative (PID) control with waste flow rate as the manipulated parameter and an unsteady-state calculation of …
