Learn why Mix Ratio of M25 Grade is NOT 1:1:2

M25 Grade Concrete Is not a Nominal Mix Concrete. M25 grade concrete is strictly a Design Mix Concrete and not a Nominal Mix concrete. It should be designed through Design Mix procedure alone. Codebook or textbook did not mention in anyplace that volumetric Mix ratio of M25 grade concrete is 1:1:2.

Concrete Mix Ratio | What Is Concrete Mix Ratio | Types of

This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.. Mixing water with this cement, sand, and aggregate will form a paste that will bind the materials together until the mix hardens. This strength properties of the concrete are inversely proportional to the water-cement ratio.
