Grade M20 concrete is recommended for residential structures due to its sufficient compressive strength compared to common brick . Additionally, M20 grade concrete has been found to have good infiltration capacity and strength characteristics that are 60% above the adequate strength of nominal concrete . On the other hand, M15 concrete samples with partial …

There are different grades of concrete designated by their compressive strength, such as M10, M15, M20, M25, and M30. The M describes the mix design and the number represents the compressive strength in N/mm2. Lower grades like M10 and M15 are used for non-structural purposes while higher grades such as M30 and M40 are used for structural elements that …

Concrete is a very important building material, and It has various grades like M10, M15, M20, M25, etc. M represents the mix and Number represents the compressive strength of concrete. Different grade of concrete has different Cement, sand, and aggregate mix ratio. So the compressive strength of different grades of concrete is different.

Nominal mixtures for concrete types such as M15, M20, M25 are generally used for small-scale construction. Large structures have high strength requirements and are therefore used for higher grades of concrete, such as M30 and above. The mixing proportions of these concretes are based on the design of the mix.
