Maha Cement OPC 53 Grade
Maha – OPC 53 grade cement, is a high strength, best quality cement designed to suit the modern construction practices. It is manufactured with excellent quality clinker, containing high percentage (56-60%) of Tri-calcium Silicate (C3S), and optimum quantity of gypsum. This cement is ideal for designing high strength, high performance concrete used in high rise buildings, bridges, flyovers, pre-stressed concrete applications, under water concreting, concrete roads etc. Due to its uniform and consistent 28 days’ compressive strength 60 MPa Maha – OPC 53 is the most preferred brand by Ready Mix Concrete manufacturers and infrastructure project engineers.
