A hydraulic Parasakti ppc 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
