The influence of curing on restrained shrinkage cracking of bonded concrete overlays
Abstract The influence of seven practical curing regimes on restrained shrinkage cracking of bonded concrete overlays was investigated. The influence of the curing regimes on the individual material properties governing restrained shrinkage cracking and on the age at cracking and crack area of ring tests and composite overlay–substrate specimens was investigated for three laboratory-made mixes of differing strengths and one commercial repair mortar. The results of the experimental testing showed that curing influences all of the material properties governing restrained shrinkage cracking. Prolonged or more effective curing was shown to either delay or reduce the rate of shrinkage respectively (dependent on the curing method), increase the tensile strength and elastic modulus, and decrease the tensile relaxation. In general, prolonged or more effective curing was shown to have a positive influence on restrained shrinkage cracking by increasing the age and net age at cracking.
