Ideally what should be the order of bulk density of PPC, 53G and 43G cement.
In our plant we have this as 53G, 43G and PPC increasingly respectively as calibrated
by outer agency. Is it OK to be bd of 43G higher than 53G?

Re: Bulk density
Dear Mr. Clark,
I am sorry that i not substantiate my query thoroughly.
In our plant we never mix flyah in 43 G cement. 43G and 53G cements
are purely OPC, none is PPC. To differentiate between 53G and 43G
only one parameter is considered and that their fineness. 53G is more fine
than 43G. At our plant its value for 43G is between 280-300 m2/kg
while for 53G its value is 301-320 m2/kg.
My query was that being more finer 53G should be having more BD than 43G.
Is''nt that case?
