MATERIALS THAT GAINS MOST OF THE STRENGTH TO CEMENT
The oxides present in raw materials when subjected to high clinkering temperature combine with each other to form complex compounds. The identification of major components is largely based on R. H. Bogues work and hence it is called as Bogues Compounds. They usually varied to get different types of Cements. The four Compounds usually regarded as major compounds are listed in following table ... ...more

PERCENTAGE COMPOSITION OF CEMENT (OPC)
Function of Cement is first to bind the sand and course aggregate together, to fill the voids between sand and course aggregate. Oxide composition of Cement (OPC) is Oxide Composition of Cement Lime (CaO) : 60% to 65% Silica (SiO2) : 17% to 25% Alumina (Al2O) : 33% to 8% Ferrous Oxide (Fe2O3) : 0.5% to 6% Magnesia (MgO) : 0.5% to 4% Sulphur Trioxide (SO3) : 1% to ... ...more
