The modulus of elasticity of PPC is lesser at the earlier stage of cementing, and greater at the later stage than OPC. PPC cement prolongs the setting time of concrete, hence help in better finishing of concrete. PPC is cheaper and more sustainable as compared to OPC. The heat of hydration of PPC is lower than that of OPC. Rice husk ash is a by-product of agriculture and is generated in rice mills. PPC is one of them with its own distinctive qualities, that make it popular all around the world. Higher grade like 53 is not recommended to be used for plastering as it is known to develop shrinkage cracks due to its high strength. Feb 23, 2018 the advantages of portland-limestone cement| concrete … portland-limestone cement has a smaller carbon footprint with no drawbacks. Since it contains more fine material, it is difficult to handle the concrete. For the manufacture of PPC, pozzolana materials such as diatomaceous earth, opaline shales, tuffs, volcanic ash, pumice stone, fly ash are used. The pozzolana present in the cement increases the fineness and decreases the water content in the cement. Cement is the soul of all modern construction. Reduction in permeability of PPC offers many other advantages, such as better durability than opc 53 cement. The treatment period of OPC is shorter than PPC hence the cost of treatment is reduced, therefore recommended where the cost-prohibitive treatment will occur. portland pozzolana cement are manufactured by using pozzolanic materials as one of the main ingredient.
