احصل على السعرPortland cement concrete (PCC) is the most widely used construction material in the world. However, the increasing emphasis on the sustainable development has highlighted the inherently adverse effects of Portland cement (PC) production on the environment and motivated researchers to explore new cementitious materials as partial or complete alternatives to PC.
