Blended cements

Blended cements



Blended cement is a hydraulic cementitious product, similar to ordinary Portland cement, but due to the addition of blending material it has certain improved properties compared to OPC. The use of blended cements improves the properties of both, fresh and hardened concrete. These can be as a result of the extended hydration of the cement- pozzolana mixture, reduced water demand, and due to improved cohesion of paste. Another important benefit is the improvement in durability resulting from the lower permeability and improved micro structure of the concrete.
