SPR-4418: Development of In-situ Sensing Method for Monitoring of Water-cement (W/C) Values and the Effectiveness of Curing of Concrete

Water-to-cement (w/c) ratio affects many concrete properties, including strength, porosity, durability, and constructability. However, w/c ratio of any given mixture can be altered during the manufacturing, transportation, and placement of concrete. This proposal aims to develop a sensing method that will enable accurate, in-situ determination of w/c ratio of freshly placed concrete and monitoring of concrete curing conditions. The successful completion of this program will result in significant cost savings to Indiana Department of Transportation (INDOT) and taxpayers.
