This guide describes specific types of concrete deterioration. Each chapter contains a discussion of the mechanisms involved and the recommended requirements for individual components of concrete, quality considerations for concrete mixtures, construction procedures, and influences of the exposure environment, all important considerations to ensure concrete durability. Some guidance as to repair techniques is also provided. This document contains substantial revisions to Section 2.2 (chemical sulfate attack) and also includes a new section on physical salt attack (Section 2.3). The remainder of this document is essentially identical to the previous “Guide to Durable Concrete.” However, all remaining sections of this document are in the process of being revised and updated, and these revisions will be incorporated into the next published version of this guide. Both terms water-cement ratio and water-cementitious materials ratio are used in this document. Water-cement ratio is used (rather than the newer term, water-cementitious materials ratio) when the recommendations are based on data referring to water-cement ratio. If cementitious materials other than portland cement have been included in the concrete, judgment regarding required water-cement ratios have been based on the use of that ratio. This does not imply that new data demonstrating concrete performance developed using portland cement and other cementitious materials should not be referred to in terms of water-cementitious materials. Such information, if available, will be included in future revisions.
