PPC at PARASAKTI CEMENT is produced Conformed
to the Indian Standards Specifications as per IS: 1489 (Part 1) - 1991 (Flyash
Based)
A hydraulic cement prepared by grinding the
mixture consisting of an intimately and uniform blend of Portland clinker and
pozzolana with the suitable addtion of gypsum or an intimate and uniform
blending of Ordinary Portland Cement and fine pozzolana material.
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
