This topic seeks to develop a device to measure total shrinkage and expansion of cementitious materials immediately upon initial stress development. The solution may include test equipment for 1) performing AASHTO T 363, 2) measuring volume change from drying, chemical, and autogenous means concurrently, or 3) another type of test equipment suited for this purpose. If optical fiber sensors are able to provide a solution, then they may be acceptable.
