(D) Portland cement is a mixture of calcium silicates and aluminates. It is manufactured by heating a mixture of limestone $(CaCO_3)$ and clay $(Al_2O_3 \cdot 2SiO_2 \cdot 2H_2O)$ at high temperatures. After cooling,the resulting clinker is mixed with a small amount of gypsum $(CaSO_4 \cdot 2H_2O)$ to regulate the setting time of the cement. Therefore,the primary components are limestone,clay,and gypsum.
