PPC provides improved workability, has less segregation and bleeding, increased water-tightness and reduced tendency of lime to leach out. It produces less heat of hydration and offers greater resistance to the attack of aggressive water containing sulphates and chlorides. It improves the durability of structures and also the strength of concrete over a period of time by making it more corrosion resistant and impermeable. It protects concrete against alkali-aggregate reaction.The minimum compressive strength of PPC after 28 days, as prescribed by BIS is 33 MPa or 330 kg Cm2. However, the ultimate, long-term strength of PPC is better compared to OPC 53. 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 as compared to OPC and it is this property coupled with its cost effectiveness that has helped in its emerging more popular in the construction industry.
