Section 2: Concrete Mix Design Texas Department of
IntroductionJob Control TestingOpening to TrafficMaturity MethodThe concrete mix design is performed to ensure that the concrete mix formulation meets or exceeds the specification requirements. The mix design is used to establish the proper proportioning of components (hydraulic cement, aggregates, water, pozzolans, and admixtures) in the mixture to achieve the specified properties. Significant concrete properties are strength, air content, slump, and the coefficient of thermal expansion (COTE). The mix design may be developed for the current project or m...
