Abstract:
Deleterious characteristics of concrete aggregate materials are reviewed, and a simplified arrangement for their classification is proposed. This arrangement is based on a recognition of harmful properties rather than on types of materials, thus providing the testing engineer with a more systematic basis for laboratory evaluation of aggregates. Harmful properties that involve chemical action are given the same emphasis as those involving the physical nature of the material. These properties are discussed in relation to the limitations of conventional methods of test and the need for supplementary testing based on petrographic and chemical techniques.
