Grade M25 is a mix of concrete with a compressive strength of 25 megapascals after 28 days.

• M25 is a standard mix of concrete used in construction.

• It is made up of 1 part cement, 1 part sand, and 2 parts coarse aggregate.

• It has a compressive strength of 25 MPa after 28 days of curing.

• It is commonly used in the construction of buildings, bridges, and other structures.

• M25 is suitable for moderate exposure conditions and c

The M-5 to M-25 ratio is a measure used in civil engineering to determine the strength of concrete mixtures.

• The M-5 to M-25 ratio refers to the ratio of cement, sand, and aggregate in a concrete mixture.

• The ratio indicates the compressive strength of the concrete after 28 days of curing.

• For example, an M-20 concrete mix has a ratio of 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts aggregate by volume.
