Effect of Coupled Mechanical-Chemical Activation on Hydration Activity of Copper Slag Powder

In order to investigate the effect and mechanism of coupled mechanical–chemical activation on hydration activity copper slag powder, powder with different grinding time content was applied prepare composite cement. The heat rate cement paste were tested for 120 h. mechanical properties microstructure samples characterized by compressive strength index, XRD, SEM. findings revealed that specific surface area increased 27.84%, 20.14%, 10.92%, respectively, when from 30 min min. particle size distribution after 90 superior index specimen extension remained constant. Chemical activator CaO further stimulated powder-based paste, promoted cement-hardened at ages. With increase in content, porosity hardened increased, resulting a decrease
