How do we get C25 concrete mix?

C25 concrete mix is achieved by combining specific ratiOS of cement, aggregates (fine and coarse), water, and additives if needed. The typical mix ratio for C25 is approximately 1 part cement, 1.5 parts sand, and 3 parts gravel or crushed stone, with water added to achieve a desired consistency and workability. To ensure the concrete reaches the required strength of 25 MPa after 28 days of curing, it is crucial to accurately measure and mix the components, and to follow good curing practices. Always refer to local standards and guidelines for precise mixing and application techniques.
