what is difference between 33, 43 and 53 grade cement..?
which is more suitable for construction and why,..??
Answer Posted / vijay kumar
I found three grades,33, 43 and 53.
A quote:
"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."
I have poured hundreds of yards of cement and did not know this.
Here is the source of the quote.
It is the eighth paragraph down when you get there.
Probably more than you want to know about cement.
