Objectives and scope

This report reviews joint practices in concrete structures subjected to a wide variety of uses and environmental conditions. Design, construction, and maintenance of joints are discussed, and in some cases, the option of eliminating joints is considered. Chapter 2 summarizes aspects of various sealant materials and jointing techniques. However, the reader is referred to AC1 504R for a more comprehensive treatment. Chapters 3-10 focus on various types of structures and structural elements with unique characteristics: buildings, bridges, slabs-on-grade, tunnel linings, canal linings, precast concrete pipe, liquid-retaining structures, walls, and mass concrete. Many readers of this report will not be interested in all types of construction discussed in Chapters 3-10. These readers may wish to first study Chapter 2, then focus on a specific type of structure.

While not all types of concrete construction are addressed specifically in this report, the Committee feels that this broad selection of types of structures can provide guidance in other cases as well. Additional structural forms may be addressed in future versions of this report.

AC1 22413 provides additional detailed discussion of both the causes of cracking and control of cracking through design and construction practice.
