Maha – Portland Pozzolana Cement (PPC) is a premium blended cement manufactured by inter-grinding the high-quality clinker with superfine processed fly ash. The clinker used here is specially made with a 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 a 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.
