Dr Iman Izadgoshasb
The use of structural adhesives, such as epoxy, for the strengthening and repair of civil infrastructure is gaining popularity in the engineering community. Of particular concern to the viability of intervention measure is the degradation of strength and durability of the epoxy over time, especially when exposed to aggressive environments. Monitoring the corrosion process of epoxy is thus essential to ensure safety of the host structure. In this paper, the electromechanical impedance (EMI) technique that employs a smart piezoelectric transducer is used to monitor the degradation process of commercially available epoxy when exposed to corrosive environments. Standard epoxy coupons with …
