What is the Difference between konark psc cement and konark ppc cement?


A brief description along with comparison of konark psc (Portland Slag cement) cement and konark ppc (Portland Pozzolana cement) cement are discussed below:

·      Konark psc cement: It is popularly known as Portland Slag Cement. It is manufactured by grinding together with “Portland cement clinker”, “Blust furnace granulated slag” as well as gypsum. Sometimes, it is also manufactured by mixing or combining with ordinary Portland cement or opc cement along with “ground granulated furnace slag” through mechanical mixers or proper blenders. It is also made up of 45-50% of clinker and 3 to 5% of gypsum. This type of cement is eco-friendly.
The konark psc cement is used in the construction of marine structures. It is commonly used in the coastal areas especially where immoderate amount of sulphates and chloride salts are found. It is known to provide resistance towards sulphates and chlorides attack. This type of cement commonly lowers the risk of cracks on the wall and maintains its durability. Thus, it is used in the construction of water dams.
Now let us discuss about the most important features of konark psc cement. The konark psc cement is famous for its high strength. It requires less amount of water. It contains the lower shrinkage properties.  
·         Konark ppc cement: It is popularly known as Portlant Pozzolana cement. This type of cement is manufactured by mixing or blending of ordinary Portland cement (opc) clinker plus gypsum along with some pozzolanic substances especially siliceous material, in a certain ratio. It is generally used in ground level.
The konark ppc cement is used for general construction related work. It is suitable for the works related to harsh environmental condition. It can be used in the construction of marine structures, mass concrete related work such as retaining pipes, sewage pipes and construction of dams. The konark ppc cement is used in brickworks as well as construction projects. This type of cement uses natural along with industrial waste to reduce environmental pollution. It is also found to be useful for plastering, as a water-proof material, tilting. It causes less shrinkgae and cracks. Residential project related construction work uses this cement.
Now the important features of konark ppc cement are: it is carefully manufactured by proper selection of particle sizes of fly ashes (pozzolana) which are ideal for durable and denser concrete. It has the property of “low heat of hydration”. It is resistance to different environmental chemicals like salt water etc. It is generally used for hydralic and marine construction.
·         The difference between konark psc cement and konark ppc cement are enlisted below:
Ø  The process of hydration is found to be slower in konark ppc cement as compared to konark psc cement.
Ø  The resistance capacity in terms of aggressive weather is found to be more in konark ppc cement than in konark psc cement.
Ø  The konark ppc cement has few important features which is pore refinement and low bleeding properties which perfect for plastering as compared to konark psc cement.
