Different types of Concrete Mix Grades, their Strength & their Uses

Within concrete mix grades, M exhibits concrete mix design ratio as well as the number next or after M describes MPa or N/mm2 compressive strength of concrete. For instance, M15, M10, M25, M20 concrete mix grades.

There are distinct sorts of concrete mix grades in civil engineering as per their requirement as well as application.

Few of them are standard as well as predesigned as well as computed however in some instances in particular instance requirement based concrete mix designs are utilized. Their applications depend on their strength. As per the kind of project, a ready mix concrete is preferred and in some instances mixing is done at site.

Concrete mix grades as well as strength

M5 concrete mix: M5 (1:5:10) is basically lean concrete mix, which can take 5 newton load/pressure on every square millimeter area or 725 pounds on every square inch.

M7.5 concrete mix: M7.5 (1:4:8) is even a lean concrete mix, which is utilized in foundation to offer plain surface and to create a disturbance amid footing as well as the level plane.

It is utilized where there is a bit more strength is required in comparison to M5 mix.

M10 concrete mix strength: Concrete mix from M10 (1:3:6) is basically ordinary concrete. It takes minimum load than in comparison to M15. Furthermore, M10 possess 10 N/mm2 or 1450 Psi compressive strength. Moreover, it is utilized in slabs, plinth beams, R.C.C walls, road pavements, and so forth.

M15 concrete mix strength: M15 possess concrete mix ratio (1:2:4) as well as it is the widely used concrete mix due to its compressive strength as well as economic conditions in ordinary concrete mix section.

M20 as well as M25 concrete ratio: About M20/M25 concrete mix ratio - M20 concrete mix ratio is (1:1.5:3) correspondingly. Moreover, M20 has compressive strength of 20 N/mm2 (MPa) or 2900 Psi. as well as M25 concrete mix ratio is (1:1:2).

M30, M40, M50 concrete mix: M30 to M50 Concrete mix are actually Standard mix. Moreover, it is mixed as per designed. That has actually excessive compressive strength.

Those are utilized in Barrages, Septic tanks, Dams, Flyovers, Bridges columns, and so forth. Moreover, that possess as excessive compressive strength of 4350 psi to 7250 psi.

To get more clear ideas, go through the following exclusive construction video tutorial.

Lecturer: Civil Engineering

M60, M70, M80 concrete mix: M60 to M80 concrete mix are high strength concrete as well as designed mix. Also, that possesses 8700 psi to 11603 psi compressive strength. Moreover, that is utilized in particular conditions.
