What is the different between OPC and PPC ?

 What is the different between OPC and PPC ?



OPC  full name: Ordinary Portland cement ?

PPC full name : Portland porozolona cement ?

Both OPC and PPC cement  used for construction purpose but those cement bogies component and setting time heat of hydration , hardness and used purpose, curing period ,grad of cement  are different.

main different opc cement and ppc cement are given below

Sl no

                 OPC Cement

                         PPC cement

1.

Opc cement initial setting time is more then PPC cement

PPC cement initial setting time is less compare to opc cement

2.

OPC cement is available in different grades, including 33 Grade, 43 Grade, and 53 Grade, which indicate the compressive strength of the cement.

PPC cement does not have specified grades like OPC cement. However, it is commonly available in the market with a standard set of properties suitable for general construction

3.

Generally RCC structure used for OPC cement, for remove form work

Generally For finishing used ppc cement

4.

OPC cement low fly ash compare to ppc cement

PPC cement is mainly fly ash based

5

OPC cement is more expense and as per designed mix and less qty required compeer to ppc cement

PPC cement is low expense as per designed mix and more quantity required compare to OPC cement

6.

OPC Cement is heat of hydration more ,curing required more ,with out curing hair crack coming

PPC Cement low heat of hydration ,curing required  but not crack is coming

7.

OPC cement Curing period is 10 to 14 days

PPC Cement curing period 7 to 10 Days

Silt Content Test as per IS Code   Take a little sand and rub the same in hand, if palm remain clean it can be assumed that sand is free of silt that called is silt content test . It is hand test. Frequency of testing  Every 20cum or more frequency as decided by engineer in charge  Permissible limit   Acceptance standard -maximum permissible limit silt content shall not be " more than 8%"  as per is code 383 and as per CPWD specification  Note: (i) If silt content is more, corrective action taken should be noted in column 10 and silt content referred after such action  and recorded in the register.             (i) Fine aggregate contenting more silt than allowable percentage shall be washed so that the silt contents are with in prescribed limit for which nothing shall be paid  Test for silt content  The method for determining silt contents is as follows:     A sample of sand to be tested shall be placed with out drying in a 200 ml measuring cylinder the volume of sample shal
