Abstract: Drying shrinkage is one of the major causes of cracking in concrete slabs. This is due to the restraining conditions that increase in severity as the distance between joints increase. Furthermore, curling or lifting of the slab at the borders due to differential drying shrinkage often leads to cracking due to traffic or loading. Though reduction in drying shrinkage empirically reduces cracking under field conditions, there is a need to be able to predict field performance based upon shrinkage performance and mechanical properties of the concrete. This will allow the engineer, contractor, and owner to take measures to minimize cracking and curling, and take advantage of increased joint spacings.
