SPR-4418: Development of In-situ Sensing Method for Monitoring of Watercement (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 INDOT and taxpayers.
