Performance Specifications for Durable Concrete

2020-9-25  To paraphrase NRMCA’s definition,2 the ideal performance specification is a set of clear, measurable, and enforceable instructions that outline the application-specific functional requirements for the hardened concrete and avoid requirements for the means, methods, ingredients, and proportions to achieve these requirements. For example, the only functional requirement for an interior building column, where durability is rarely an issue, might be minimum compressive strength. The functional requirements for a bridge deck, however, might include minimum strength, low permeability, scaling resistance, a low amount of cracking, and other criteria related to durability. Of course, verification of these functional requirements will require that test methods and acceptance criteria are clearly defined, with some testing required for prequalification and some for job-site acceptance both before and after the concrete is placed. Instead of the detailed list of mixture ingredients typical of submittals for a prescriptive specification, the submittals for a performance specification would be a certification that the mixture will meet the specification requirements
