1. Fineness of cement. 53 grade fineness compare than to 43
grade cement.
2.compressive strength of concrete.
3.Low content gypsum so, 53 grade Fast Harding compare than
to 43 grade.

Answer / deepthi ramachandran

The grade 43 and 53 in cement mainly corresponds to the
average compressive strength attained after 28 days ( 6724
hours) in mega pascals (Mpa) of at least three mortar cubes
( area of face 50 cm squared) composed of one part cement, 3
parts of standard sand( conforming to IS 650:1966) by mass
and P/4 (P is the percentage of water required to produce a
paste of standard consistency as per IS standard) + 3
percentage ( of combined mass of cement plus sand) of water
, prepared, stored and tested in the manner described in
methods of physical test for hydraulic cement.

721 hr not less than 23 MPa for 43 grade, 27 MPa for 53 grade

1682 hrs not less than 33MPa for 43 grade, 37MPa for 53 grade

6724 hrs not less than 43MPa for 43 grade, 53 MPa for 53 grade

Answer / atul bansal

53 grade cement concrete contain more heat of hydration than
43 grade cement concrete due to more surface area for
chemical reaction so more curing and precious work required
in 53 grade of cement concrete than 43 grade cement concrete

Answer / yamini

for 28 days strength of 43 grade is 43mpa
53 grade is 53mpa

Answer / sridhara.n

The 53 Grade Cements Settles faster than the 43 Grade.

Answer / subzar

Coforming to strength
attained after 28 days in Mpa.

Answer / matu singh chauhan

43 grade-it can be used up to M30grade concrete.it is used
in precast elemant ,53 grade-it can be used more than M30,
it is used in morine structure

Answer / vijay

1.
43 GRADE IS USED IN NORMAL STRUCTURES,
WHILE 53 GRADE IS USES IN WATER BODIES, COZ ITS SETTLEMENT IS MUCH FASTER
2.
43 GRADE HAS A COMPRESSIVE STRENGTH OF 43MPA IN 28DAYS
ND
53 HAS 53 MPA
