UltraTech Cement PPC

Portland Pozzolana Cement (PPC) makes concrete more impermeable, denser as compared to OPC. The long-term strength of PPC is higher compared to OPC. PPC produces less heat of hydration and offers greater resistance to the attack of aggressive waters than normal OPC. PPC can be used for all types of construction. Portland Pozzolana Cement (PPC) PPC is a type of blended cement. It consists of 15-35% pozzolanic material, 4% gypsum and the rest is clinker. PPC as per BIS code is equivalent to that of 33 grade. Since the pozzolanic material reacts with calcium hydroxide liberated by the hydrating Portland cement and forms cementatious compounds, PPC makes the concrete more impermeable and denser. It can be confidently employed in construction of hydraulic structures, marine works, mass concreting etc. It protects concrete against alkali-aggregate reaction.
