Abstract: A system has been developed to study the effects of the physical environment on concrete. This system is designed to continuously measure the total length change in a concrete specimen due to wetting and drying, temperature change, and freezing and thawing. Dilation is the increase in length of concrete as it is cooled into the freezing range of contained water. Dilation in a specimen exceeding 50 microin/in. is considered critical and may damage the specimen. The system, therefore, was designed to have a sensitivity of at least 10 microin. Numerous dilation tests were conducted on moist specimens to determine the magnitude of dilation and to proof test the system. These data are included in this report.
