Abstract:

Cement is widely used everywhere for construction purposes and quality comparison of different ordinary Portland cements is very important. Five different brands of cement were tested for their chemical constituents such as silica, alumina, iron, calcium, magnesium, sulfates, insoluble residue, free lime and loss on ignition with American standards for testing and materials (ASTM). Results for five locally produced Portland cements revealed that the chemical compositions of most cement as determined by standard methods lie within standard limits. But the difference in constituents of various brands of cements is due to quality control setup differences of different cement plants.
