Portland Pozzolana Cement (PPC)

Portland Pozzolana Cement (PPC)



Features:

TNPL’s PPC cement has high strength, durability and resistance as it is produced by inter-grinding processed fly ash and gypsum. The high binding properties and increase in workability during concrete mixing gives this widely used cement, an edge over others. The fly ash content in PPC cement presents high corrosive resistance and increases the life cycle to the buildings. PPC cement is used for a wide variety of applications that ranges from commercial and residential complexes, bungalows, foundation, columns, beams, slabs, RCC elements and mass concreting.
