Application of concrete electrical resistivity technique for monitoring thesetting and hardening of concrete

The measurement of concrete electrical resistivity is a very fast method providing reliable information about the pore structure and durability parameters in concrete. This measurement can be related to the setting of concrete. Time of setting when concrete’s workability decreases significantly is an important parameter for concrete production in different climates and construction conditions. This project is designed in order to better understand the underlying mechanisms in concrete setting as it is related to the electrical resistivity of this material. Three students will work on various aspects of this project, including the correlation of setting and resistivity, optimizing the electrical current frequency for various concrete mixtures, and application of electrical resistivity in determining the time to remove concrete formwork. This project will ultimately result in the development of a comprehensive guideline for the application of electrical resistivity measurement for the improvement of current quality control practices in the construction industry.
