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..

Answer / debasish pramanick

In the designation of a concrete mix,letter M refers to the mix and the number to the specified characteristic compressive strength of 15 cm. cube at 28 days,express in N/mm2.As a example M25 = 25 N /mm2 or 250 Kg./cm2 (app).

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.
