Answer / nagesh raj
M- 40 is strongest It depends upon the design mix, . M-40
means its strengthis 40n/mm2
Is This Answer Correct ? | 68 Yes | 7 No |
Answer / ravi
Strengh of M20 = 20 MPa
Strengh of M25 = 25 MPa
Strengh of M30 = 30 MPa
Strengh of M35 = 35 MPa
Strengh of M40 = 40 MPa
So, M40 has the highest strength. When the grade of concrete is directly given, mix ratio doesnt come into picture. We use proper mix to get the desired grade of concrete.

Answer / mani
M means mix,and numerical value give the strenth of
concrete in n/mm2.therefore higher the value of mix,higher
the compressive strenth of concrete.M40
