what are the diffrent kind of grades in concrete and what does M means while specifyng the grades?..

Answer / ajay prasad

Ordinary concrete- M10,M15,M20
Standard Concrete-M25,M30,M35,M40,M45,M50,M55
High Strength concrete-M60,M65,M70,M75,M80
Here are two grades also specified in BIS for lean concrete
M5 and M7.5
Where M refers to Mix and the given no. specified the
characteristics compressive strength of 150 mm cube after 28
days curing on normal temperature..

what are the diffrent kind of grades in concrete and what does M means while specifyng the grades?..

Answer / vaibhav mulay

Letter M represents mix (concrete mix) and the number followed after M represents the compressive strength to be attained in N/sq.mm at 28 days age when a standard cube of 150x150x150 mm is subjected to standard compressive test. Both combinedly termed as Grade of Concrete.

Thus, a concrete of M30 grade should attain a compressive strength of 30 N/sq.mm at 28 days age.
