Detachment diagnosis by percussion frequency characteristics based on actual construction skills.

Part2 Frequency characteristic and adhesion resistance in pseudo float tile.

Abstract

In the previous report (Part 1), we reported the effectiveness of the correlation evaluation between the percussion anti-sound frequency characteristics and the peeling deterioration properties. Against this background, in order to consider creating a correlation evaluation criteria Bond Behavior frequency characteristic, to produce an outer wall tile simulative test product having a floating portion was measured adhesion strength between percussion rebound sound frequency. As a result, it was confirmed that there is a relationship between the frequency characteristics and the adhesion strength that the primary peak frequency decreases as the adhesion strength decreases, and the possibility of estimating the adhesion strength at the primary peak was considered, so we will report on them.
