Concrete Mix Design in Construction: The Specification That Determines Performance, Cost, and Durability

Concrete mix design specifies cement, aggregates, water, admixtures, and proportions to achieve required strength, workability, and durability. Specifications include compressive strength (psi), slump, air content, and specific exposure requirements. Understanding concrete mix basics helps GCs review specs, evaluate submittals, and coordinate concrete operations effectively.
