Research on the Properties of Composite Portland Cement with High Volume of Industry Waste

摘要

The paper studied the influences of some industry wastes on the properties of composite Portland cement. Different amount of wastes were added as cement mixture. Through the investigation of properties of cement by orthogonal experiments, the optimum combination was obtained. The hydration products were analyzed by XRD and SEM. Its hydration mechanism was investigated and the result shows that with appropriate ration of each influencing factors, the cement could meet the national standard 42.5MPa of cement strength.
