WebThe density of OPC cement is = 1440 Kg/m 3. Also Read – Difference Between OPC and PPC Cement. Sand Density. ... Apparent specific gravity = (Weight of oven-dried Aggregate at 100°c for 24 hours) / (Weight of water’s volume equal to that of aggregate’s solids excluding permeable pores) Web28 de mar. de 2024 · PPC has a slow hydration process due to which heat generation is comparatively lower. Cost. OPC is more costlier than PPC. The price of PPC is less which makes the construction economic. Permeability and Fineness. Lower the fineness , higher the permeability. OPC has a fineness of 225m 2 /kg.
