Abstract | Concrete slabs on grade tend to curl up at joints and around the perimeter. As a result, floors in industrial and commercial buildings may deteriorate rapidly, causing safety problems and requiring repairs. This Update reviews the basic cause of curling - differential shrinkage produced as the exposed top surface shrinks and the core does not. Factors affecting the amount of curling are listed and discussed, along with possible preventive measures. Readers are advised that, although it is possible to repair most slabs, curling should be minimized by careful control of concrete mix composition and handling. Options are explained for controlling curling, preventing damage to curled slabs and deciding on a repair strategy. Finally, various methods of repair for different situations are discussed. |
