    THE CONCRETE PORTAL: Concrete is the most widely used material in the world after water. For thousands of years, concrete has been used for construction of landmark monuments. Most of these structures have suffered the ravages of war as well as the aggressiveness of the environment, and yet have withstood the test of time, owing to the

    Compositionof modern cements is usually characterized by markedly higher C 3S/C 2S ratios than in older cements. Concretes made with these cements and specified in terms of 28-day strength usually only satisfy these specifications at higher water-cementratios than concretes made with older cements

    CementManufacturing. RAW MATERIALS.COMPOSITION. Portlandcementconsists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminium oxide, Al 2 O 3).The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material
