Abstract: 
This paper describes the use of x-ray attenuation measurements to monitor and quantify the movements of reinforcement corrosion products into mortar. X-ray attenuation measurements are also capable of detecting cracks. Therefore, this approach provides a direct measurement of the amount and location of reinforcement corrosion products required to induce cracking. Corrosion is induced by direct current to the embedded reinforcement. Results of a parametric investigation on the impact of water-to-cement ratio (0.30, 0.40, and 0.50) and corrosion rate are presented.
