Concrete mix design is a systematic process of selecting the right proportions of ingredients to create a concrete mix with the desired properties, strength, workability, and durability for a specific construction project. The goal of concrete mix design is to achieve a balance between the various components while meeting project requirements and ensuring the optimal performance of the concrete.

The key components of a concrete mix design include cement, aggregates (sand, gravel, crushed stone), water, and sometimes supplementary cementitious materials (e.g., fly ash, slag, silica fume) and chemical admixtures.
