Design mix M25 is a concrete mix with a compressive strength of 25 MPa after 28 days.

• M25 mix consists of 1 part cement, 1 part coarse aggregates, and 2 parts fine aggregates.

• Water-cement ratio should be maintained at 0.5 for M25 mix.

• M25 mix is commonly used in construction of buildings, bridges, and roads.

• The mix should be properly cured for at least 28 days to achieve the desired strength.
