Developed with monomolecular layer technology, it forms a nano passive layer over the steel surface very quickly before other elements that come into contact with steel could reach the surface. It deflects chlorides and water molecules causing corrosion, thus guarding against rusting of steel surfaces in the concrete.

In ordinary concrete, calcium hydroxide liberated during hydration leaches out as concrete hardens. This results in the formation of interlinked voids in the concrete and makes it permeable. In TOPCEM SDC the fly-ash through its pozzolanic properties reacts with calcium hydroxide and forms insoluble cementitious compounds. This process reduces and blocks the voids, thereby reducing the permeability of the concrete. The reduced permeability of concrete provides better resistance against sulphates, chlorides and frost action. Thus, TOPCEM SDC provides a strong, durable and long-lasting structure.

Topcem SDC gives more coverage, higher strength, less cement consumption for targeted strength due to higher Blaine & fineness. Smaller particles of Topcem SDC react with water to produce strength inducing compounds. In ordinary cement with bigger particles, the products of reaction accumulate on the surface, leaving the inner portion unused and leads to loss of strength.

Use of BOPP (Biaxially Oriented Polypropylene) bags makes it impossible to tamper with and make sure there is no wastage of cement. Special packaging makes it moisture and spill proof to ensure that you get 50kg of assured best quality cement to use in your project.
