Abstract:Shrinkage cracking is a widespread problem in concrete building walls. The stresses and resulting cracking are a function of the shrinkage and degree of restraint, most commonly from the foundation. A technique was developed for determining shrinkage stresses using rubber models. The values were checked by observing crack patterns in mortar models. Remedial measures were tried, and some gave encouraging results. A new ring test for the crack resistance of concrete was tried and showed promise.
