This report reviews the state of the art in design, construction, and maintenance of joints in concrete structures subjected to a wide variety of use and environmental conditions. In some cases, the option of eliminating joints is considered Aspects of various joint sealant materials and jointing techniques are discussed. Chapters in the report 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. Keywords: bridges, buildings, canal linings, canals, concrete construction, construction joints, contraction joints, design, environmental engineering concrete structures, isolation joints, joints, parking lots, pavements, runways, slabs-on-trade, tunnel linings, tunnels, walls.
