PERFORMANCE-BASED CONCRETE MIXTURES AND SPECIFICATIONS FOR TODAY

Strength, constructibility, durability and architectural appearance are the four primary performance objectives for concrete mixtures. The designer must identify the project performance objective and there must be a means whereby a supplier/contractor can meet the objective using accepted methods and local materials. This article suggests an aggregate selection method that makes the best use of local materials to reduce costs and extend infrastructure serviceability. Mix data for many types of concrete construction have been collected and graphically analyzed. The aggregates used in the study were equidimensional crushed stone, natural gravel and sand. From these data, a model performance-based mixture design has been developed that will satisfy the needs of most normal-strength concrete cast in the United States. The mixture design identifies the mixture and prescriptive requirements for materials, strength and air content.
