STRESS AND CRACKING IN CONCRETE DUE TO SHRINKAGE

A method has been developed for calculating the stress in concrete which arises from linear-elastic restraint to shrinkage. Such stress depends on the rate and amount of shrinkage and creep and on the stiffnesses of the concrete and restraint. The relative importance of these factors is examined. Experiments on a particular concrete have verified that the method can predict stress and hence can indicate the likelihood of cracking. /TRRL/
