How do you create mix concrete strength c25?

To create C25 concrete, you typically use a mix ratio of 1 part cement, 2 parts sand, and 4 parts aggregate, with water added to achieve the desired consistency. The water-cement ratio should generally be around 0.5, meaning for every 1 part of cement, you add approximately 0.5 parts water. Ensure thorough mixing to achieve uniformity, and consider adding admixtures if necessary to enhance properties like workability or curing time. Always perform tests to ensure the concrete meets the C25 strength requirements.
