The performance of Portland cement in concrete or mortar formation is very well influenced by chemical compositions among other factors. Many engineers usually have little information on the chemical compositions of cement in making decisions for the choice of commercially available Portland cement in Ghana. This work analyzed five different brands of Portland cement in Ghana, namely, Ghacem.Importance of cement as a construction material, and the geographic abundance of the main raw material, limestone, cement is produced in virtually all countries.  Every 1 ton of cement produced leads to about 0.9 tons of CO 2 emissions and a typical cubic yard (0.7643 m3) of concrete contains about 10 by weight of cement.
