    Abstract

    A detailed outline of the various factors that may influence concrete durability has been prepared by Subcommittee II-d on Durability of Concrete of ASTM Committee C-9 on Concrete and Concrete Aggregates. The complete tabular outline is appended to this paper. The factors are subdivided into five major groups: 1. The physical properties of the hardened concrete, 2. The constituent materials of which the concrete is composed, 3. The construction methods used in fabricating or building the structure, 4. The nature of the deteriorating influences to which the structure will be exposed, and 5. The type of loads which the structure is designed to carry and to which it will be subjected during its useful life. Not all of these factors are of equal significance in their effect upon the durability of the concrete structures. Some are obviously of major importance, others are reasonably well understood, but many that might exert a major role in determining the life of the concrete have, to date, been almost entirely ignored. Although this outline was included in another paper2 by the author, it is believed that a discussion of the general aspects of the significance of tests and properties of hardened concrete that relate to resistance to weathering can still best be based on that outline. Many of the some hundred items of the outline are discussed in other papers included in this publication.
