M10 is a grade of concrete that corresponds to a mix ratio of 1 part cement, 3 parts sand, and 6 parts coarse aggregate. This mix is typically used for low-strength applications such as pavements, footpaths, and non-structural works.
The grade of concrete is determined by the compressive strength it achieves after 28 days of curing. For M10 grade concrete, the mix ratio ensures that the strength is around 10 MPa (megapascals), which is sufficient for non-load-bearing applications.
The correct proportions are essential to ensure the workability, strength, and durability of the concrete. The mix ratio is determined based on the type of work being done, the materials available, and the expected loads on the concrete.
