Mahacement - Durability That Lasts For Generations
Maha Cement _PPC

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.
