Influence of Material Properties of Reinforced Concrete Element on Acoustic Emission due to Corrosion

Shilpa Vishal Patil

Abstract


The material properties of reinforce concrete (RC) influence the corrosion process of steel rebar and subsequent cracking of concrete. This paper investigates the influence of material properties on acoustic emission (AE) due to corrosion of rebar in concrete. RC cylinders with various cover thickness to rebar diameter ratios (C/D), cement types and steel types were studied to identify their influence on cumulative signal strength (CSS) of AE technique. The result of analysis of variance (ANOVA) indicated significant effect of steel type on CSS values due to corrosion followed by cement type, whereas C/D has no significant effect.
