Developing Time Domain Reflectometry (TDR) Instrument for Fresh Concrete and Early Stage Concrete

This research explores the use of Time Domain Reflectometry (TDR) to measure a variety of properties related to performance of fresh concrete and early stage concrete. These include rapidly measuring the water content of fresh concrete, monitoring the evolution of free water content during curing estimating the time of initial setting and final setting, estimating the transport properties, and predicting the strength development of early stage concrete. Additional applications are being identified in the course of this research to ensure construction of high quality infrastructure under different conditions.
