The principal causes of cracking and recommended crack-control procedures are presented. The current state of knowledge in microcracking and fracture of concrete is reviewed. The control of cracking due to drying shrinkage and crack control in flexural members, overlays, and mass concrete construction are covered in detail. Long-term effects on cracking are considered and crack-control procedures used in construction are presented. Information is presented to assist in the development of practical and effective crack-control programs for concrete structures. Extensive references are provided. Keywords: aggregates; anchorage (structural); bridge decks; cementaggregate reactions; concrete construction; concrete pavements; concrete slabs; cooling; corrosion; crack propagation; cracking (fracturing); crack width and spacing; drying shrinkage; shrinkage-compensating concrete; heat of hydration; mass concrete; microcracking; polymer-modified concrete; prestressed concrete; reinforced concrete; restraint; shrinkage; temperature; tensile stresses; thermal expansion; volume change.<\/p>\n
