PPC at PARASAKTI CEMENT is produced Conformed to the Indian Standards Specifications as per IS: 1489 (Part 1) – 1991 (Flyash Based)
This type of hydraulic cement is manufactured through a process of grinding a carefully balanced mixture of Portland clinker and pozzolana, with the addition of gypsum to create the ideal consistency. Alternatively, PPC can also be created by blending Ordinary Portland Cement with a fine pozzolana material. The resulting product is known for its excellent durability and strength, making it a popular choice for a variety of construction projects.
The Cement mortar that is prepared in 1: 3 proportions using standard sand (as per IS:650) and tested at standard laboratory conditions and should gain the compressive strength of not less than 33 MPa after 28 days,
- Produces less heat of hydration and offers resistance to the attack of aggressive waters.
- Higher fineness Improves the permeability of the concrete and hence durability
- Increases the resistance to corrosion of reinforcement
- Improves the pore size distribution & Reduces leaching of calcium hydroxide liberated during cement hydration thus reducing the leaching.Reduces the micro cracks at the transition zones
