Abstract

This study investigated the evolution of electro-mechanical impedance (EMI) of piezoelectricity (PZT) sensor embedded in hydrating steel fiber reinforced mortar to determine the setting times of that. Penetration resistance test was also conducted in order to justify the valid of EMI sensing technique. As a result, the setting times of steel fiber reinforced mortar can be effectively monitored through the EMI sensing technique using PZT sensor.
