Apr 25, 2021 Let us be clearer with an example of M25 grade concrete mix ratio. The proportions of cement in M25 grade of concrete is as follows- 1 part of cement, 1 part of sand or fine aggregates, 2 parts of coarse aggregates, and Required quantity of water. Mixing the cement, sand amp aggregates in the following proportions will result in M25 grade concrete.

WHAT IS M25 GRADE CONCRETE M25 grade concrete, unlike M15 and M20, is a standard type of grade concrete.M25 grade concrete is a higher grade concrete than M20. PROPERTIES OF THE M25 GRADE CONCRETE M25 is a mixture composed of cement, fine aggregates and coarse aggregates with a ratio of 112 is 1cement, one sand, and two aggregates.
This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent.
