Answer / ravindra wakodikar
( Here we are talking about cement not about concrete )
grade given here isn't the compressive strength but it is the fineness of the cement .
" 53 grade would be more finner than 43 grade cement "
53 grade cement would generate more heat of hydration ,developing strength at rapid rate ,however the final strength of both the grade will be same.

Answer / sanjay kumar
I found three grades,33, 43 and 53.
"In fact, all cements are one and the same but for minor
changes in the characteristics. By and large grade 33 cement
would meet the structural requirements of ordinary and small
scale consumers. 43 grade cement may be utilised for precast
concrete production besides the sleeper manufacturers and
other building components producers, 53 grade., cement may
be utilised by builders of heavy infrastructure such as
bridges, fly overs, large span structures and high rise
structures. The common man's perception that 53 grade.
cement is the best cement is not only due to the aggressive
marketing strategies of the cement manufacturers but also on
the presumption that the heat generated during hardening of
concrete is an index of its quality. When 53 grade., cement
is used the heat generated is very high. Hence, consumers
believe that it is a better cement when actually it is not
so. Each cement has to be chosen for a particular use."

Answer / bhausaheb mane
it is very simple 43 and 53 grade of cement
means,compressive strength of that cement wiil be minimum
43 N/mm2 for 43 grade and 53 N/mm2 for 53 grade cement.
after mixing of 1:3(cement:sand)ratio and after 28 days

Answer / dr. paul morton-thurtle
Not quite right. Exactly, in the SI units, the number after
the C represents mega, or million, pascals per square metre
in the mgs system. Mpa. I agree that a square metre is a
million square millimetres, so yes, 35Mpa, or 70Mpa or
whatever does divide by 1 million to give per square
milimetre. So, yes, C? can be pere square millimetre, but
this is not exactly what is meant by the defibition. A
pascal is the SI unit of pressure and is 1 newton per square
metre. In the industry, we use the mgs system, which is
metre - gramme-second.
