It has equally good properties as OPC. The only difference between OPC and PPC is that PPC uses flyash as an ingredient up to the prescribed limits set by Indian Standards. There is no reason why you should not use PPC.<BR/><BR/>And, in fact, there is quite a possibility that you will get only PPC in the market as OPC production is minimal in almost all of cement plants, and whatever OPC is being produced otherwise, is probably already earmarked for Govt. agencies and projects.<BR/><BR/>For any other query/clarification, please feel free to ask.Team@Bricks-n-Mortar.comhttp://www.blogger.com/profile/09178701687883616037noreply@blogger.comtag:blogger.com,1999:blog-4783811606552237774.post-73289337653547595482008-06-24T18:44:00.000+05:302008-06-24T18:44:00.000+05:30Pls guide if I should buy OPC or PPC for renovation purposes.
