    Hi all ,
    Ccan anyone tell me analytical difference between OPC , PPC & PSC Cement ?
     
  2. OPC - Oridinary Portland Cement usually used above ground level normally
    PPC - Porzzolna Portland Cement usually used below ground level.
    SRC - Sulphate Resistant Cement usually used depending on on climatic and conditions

    hope this helps..

    whats you think about initial planning stages of any construction ...what we as a civil engineer sgould hire and do?

    SRC used where the concrete is exposed to the risk of deterioration due to sulphate attack, for example, in contact with soils and ground waters containing excessive amounts of sulphates as well as for concrete in sea water or exposed directly to sea coast.
    Refer IS: 12330 - 1988
    Sulphate Resisting Cement can also be used in mass concrete where reduced heat liberation is required.
     
  7. If you want exact technical gyan, then here you go.

    OPC (Ordinary Portland Cement) is the basic type of cement with around 95% of clinker and 5% being gypsum which is added as an additive to regulate setting time of cement. It comes in three grades (OPC 33 ,43 & 53). OPC 53 Grade means the minimum compressive strength requirement is 53 MPa at 28 days.

    PSC or Portland Slag cement is a kind of blended cement manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement.

    Normal composition of Portland slag cement is 40 % clinker, 5 % gypsum and 60 % blast furnace granulated slag. As per IS:455 ,the quantity of GGBS can be in the range to 25 % to 70%. The minimum compressive strength requirement if 33 MPa at 28 days for PSC Cement. PSC cement has less heat of hydration as compared to OPC cement.

    OPC is used used above ground level
    PPC is used below ground level
    the use SRC usually used depending on on climatic and conditions

  9. Ordinary Portland Cement (OPC) is the most common cement used in general concrete construction when there is no exposure to sulphates in the soil or groundwater.

    The Portland Pozzolana Cement(PPC) is a kind of Blended Cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions

    Portland Slag Cement(PSC) is produced by mixing Portland cement clinker, gypsum and granulated Blast Furnace slag in suitable proportions and grinding the mixture to get a thorough and intimate mixture between the constituents.

    In which conditions we prefer PSC
