Abstract:
The performance of any cement brands is a function of its physical and chemical characteristics. Cement oxides are the chemical residues and components that activate the concreteness of the materials. Five brands of Portland cement; Elephant, Unicem, Dangote, Eagle, and BUA were investigated to determine the level of their oxide in the compound state. The results show that all the five brands examined to meet the ASTM C150-07 Standard requirements for cement oxides (oxygenated compounds) (SiO2, CaO, Al2O3, MgO, Fe3O2 & SO2) as two (Dangote and BUA) out of the brands were above Fe3O2 limit with ASTM C150-07 standards. The entire five brands can be optimized with additional practical approach(s) that prevent cracking.
