Answer / shakti

It is the grade of the cement i.e,it implies that the
strength of cement achieved after 28 days of curing will be
43mpa & 53mpa respectively.

Answer / n.rajeev d.c.e

43&53 is grade of the cement

Answer / pinakin

Characteristic compressive strength after 28 days

Answer / nirbhay kumar

43 AND 53 ARE CEMENT GRADES.

Answer / n.rajeev

That is grade of cement. like how we speak concrete grade.

Answer / madhu sudhan reddy

ITS REFER THE MINIMUM COMPRESSIVE STRENGTH OF THE CEMENT AFTER CURING THE 28 DAYS AT NORMAL TEMPERATURE....

Answer / emdadul haque

The number (43&53) to the specified Characteristic
compressive strength of 150mm size cube at 28 days,
expressed in N/sqmm.

Answer / munish neb

43 & 53 grade has no relation to its compressive strength. These grade gives the fineness modulus of the cement. More finer cement ,it settle early and have hydration of heat is more that's why 53 grade need more curing than 43 grade. After 28 days, the strength of the all grade cement is same.

Answer / mitraj

53 grade cement produce more heat of hydration then
43...henc its not good then 43 grade......
