Project specifications, reference publications, drawings, and other contract documents contain the requirements for concrete materials, proportions, and characteristics. Concrete mixtures intended to satisfy these requirements are usually submitted based on field test results, laboratory trial mixture data, or both. The purchaser’s acceptance of mate-rials and mixtures is based on conformance of the submitted details to the criteria contained in the contract documents.This guide provides information to assist in the submittal and review of materials and concrete mixture proportions. It is intended to benefit both the submitter and the reviewer.
This guide is limited to the preparation and review of the submittal of proposed materials or concrete mixture propor-tions for conformance with the requirements of the contract documents. Quantitative proportions need only to be submitted when required by the contract documents. There are two types of submittals: prescriptive and performance.
Cementitious materials, aggregates, admixtures, fibers, and water should comply with the requirements stipulated in the contract documents. If a substitution is deemed neces-sary or desired from the specified material, such deviation will be elaborated along with appropriate documentation that the concrete will be of equal or better performance.
