Tower Type Sensor (TTS) was developed to monitor the depth-related electrical resistivity in chloride-contaminated cement mortar using an electrochemical impedance spectroscopy (EIS) method. This paper also details the arrangements of TTS. Then sensor geometric constant k was determined in 0.01 mol/L KCl solution. According to the modified equivalent circuit characteristics of TTS system embedded in the cement mortar, a frequency range from 20,000 Hz to 100 Hz is recommended instead of traditional constant frequency which is found to be less accurate due to neglected interface capacitance.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
