Plastic shrinkage and plastic shrinkage cracking sometimes occur in the exposed surface of freshly-placed concrem. This shrinkage and cracking is caused by a rapid evaporation of water from the surface of the concrete. Conditions that determine the rate of evaporation arc described. Construction procedures and practices that can minimize the causes of this type of shrinkage and cracking are recommended. Specific cases cited show how application of these procedures has solved the problem. It is believed that the recommended corrective measures will solve the problem of plastic shrink-age and plastic shrinkage cracking on construct,ion projects.
