### Grade Of Concrete And Their Type Of Grade - Civil Knowledges

Types of grade. Materials are mixed in specific proportions to obtain the required strength. The strength of the mix is specified as M5, M10, M15, M20, M25, M30, etc, where M signifies Mix and 5, 10, 15, etc. as their strength in kN/m 2.In the United States, concrete strength is specified in PSI which is Pounds per Square Inch.

Grade Of Concrete. Concrete is generally graded according to its compressive strength as per IS-156,2000 there are fifteen grades (M10 to M80) of concrete in the designation of concrete mix, the letter M refers to the concrete mix and the number refers to the specified characteristic strength of concrete at 28 days expressed in MPa.

Learn More### What is M in grade of concrete?

Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
