Maha Cement – OPC 53 grade

Maha Cement – 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. It is the most preferred brand by Ready Mix Concrete manufacturers and infrastructure project engineers.

Details:

Maha HD+ is a brand new variety of cement, which offers various application advantages over other cement. Maha HD+ is manufactured by mixing special mineral admixtures, granting it superior technical properties.

Choose Maha HD+

• for brilliant concrete workability and improved concrete cohesiveness.
• for its high early and later strength.
• for its low heat of hydration which prevents the generation of excess heat and surface cracks
• for its high sulphate-resistant properties which makes it ideal for harsh environmental conditional

Maha HD+ is perfect for

• mass concrete projects like dams.
• all types of commercial and industrial structures like beam, column, plastering, etc.
• precast concrete pipes and blocks.
• waste water treatments & marine applications.

Maha Cement PPC

Maha Cement – Portland Pozzolana Cement (PPC) is premium blended cement manufactured by inter-grinding the high quality clinker with superfine processed fly ash. The clinker used here is specially made with high percentage of Tricalcium Silicate C3S (58-60%). Only high quality fly ash from select chambers of Electrostatic Precipitators (ESPs) are extracted and transported in closed bulkers is used to manufacture Maha Cement. Clinker and fly ash with desired proportion of gypsum is inter-ground in high efficiency closed circuit Ball Mills. The “O-Sepa”and SKS separators used in the mills enable us to maintain high fineness (about 350 m2/kg) and good particle size distribution (PSD). Maha Cement thus manufactured surpasses the compressive strength requirement of OPC 53 grade at 3, 7 and 28 days while enabling you to get excellent durability in concrete.
