Abstract: Concrete and other cementitious materials are susceptible to volume changes in response to temperature variation, moisture changes, and chemical reactions. These volume changes result in the development of tensile stresses that can ultimately lead to cracking. Historically, ring tests have been used to provide qualitative comparisons of shrinkage cracking between concrete mixtures. More recently, instrumented rings have been used to measure the magnitude of tensile stresses that develop inside the material to better quantify early-age cracking potential. This paper reviews recent developments in quantitative ring analysis and describes emerging advancements in testing and data analysis procedures that can account for material variability, ring eccentricity, and the potential expansion of specimens at early ages.
