GAJ PPC Concrete Cement​

Portland cement clinker is intimately blended with specified quantities of gypsum and pozzolanic materials (e.g. Fly Ash) to produce Portland Pozzolana cement. Pozzolanas by themselves do not have cementitious properties but reacts with calcium hydroxide in the presence of moisture at normal temperature to form compounds having cementitious properties. The concrete produced by using Portland Pozzolana cement has high ultimate strength, is more durable, resists wet cracking, thermal cracking and has a high degree of cohesion and workability in concrete and mortar.
