- Grade of concrete is defined as the concrete mix proportion, and the minimum compressive strength of concrete, at the end of the 28-day curing period.
The compressive strength of the concrete is the maximum amount of strength, a concrete develops after 28 days to resist the crushing force or axial force on it before reaching its failure point.
Test for compressive strength is carried out either on a cube or cylinder. Various standard coderecommendsenda concrete cylinder or concrete cube, as the standard specimen for the test.
The M standard signifies the cube sample size of concrete, while the C standard signifies the cylindrical sample size of concrete. The C standard can also be used as a cube and cylindrical sample size.
The mix ratio of concrete is the proportion by volume of cement, sand, and coarse aggregate, that is needed to produce a concrete grade in the presence of adequate water.

Very educative
Thank you for taking the time to create this video. It was very useful.
More like our Concrete test this semester❤
Nice informative video
thank you very much
Hi. Thanks for your video. I am looking for the source documentation regarding your chart listing the various mix especially for Grade 30,35 and 40 concrete. Thanks.
Worked on a research project years ago where we created a formulation that tested at 130 MPA.
It was insane how strong it was, and so simple! :)
