(A) Portland cement is primarily composed of calcium silicates and aluminates. The main constituents are tricalcium silicate $(3CaO \cdot SiO_2)$,dicalcium silicate $(2CaO \cdot SiO_2)$,tricalcium aluminate $(3CaO \cdot Al_2O_3)$,and tetracalcium aluminoferrite $(4CaO \cdot Al_2O_3 \cdot Fe_2O_3)$. Among these,$CaO$ and $SiO_2$ are the most abundant components,with $CaO$ typically accounting for approximately $64 \%$ and $SiO_2$ for approximately $21 \%$ of the composition.
