Abstract

An embedded piezo sensor has high sensitivity, higher longevity, low cost and special encapsulation to the sensing element such that it is protected against deterioration by water. Its application of selfsensing mechanism technology is aimed at achieving high performance, better and more reliability and uniform quality. In this study different blended concrete cylindrical specimens were prepared to investigate the rebar corrosion assessment comparison of two different piezo configurations (surface bonded and embedded) in blended concrete. Experiments are conducted on different blended concrete on which piezo sensors are surface bonded on rebar and embedded in the surrounding of the rebar inside the concrete to compare the sensing capability of the two configurations. A series of accelerated corrosion tests have been performed on reinforced cylindrical concrete specimens. The equivalent stiffness parameter and the statistical index are being compared for the two types of sensor configurations. The experimental results based on the qualitative and quantitative analysis shows that the surface bonded and embedded piezo sensor assessed corrosion and are complementary to each other.
