THE INVESTIGATION OF ASSESSING THE DEGRADATION STATE OF SEALANT APPLIED TO HIGH-RISE BUILDINGS CONSTRUCTED MORE THAN TEN YEARS AGO

Abstract

Recently, the number of extensive repair work in high-rise building increases. Assessing the degradation state of sealant in high-rise building is usually performed by visual observation used by gondola that provides only a cursory evaluation of the product. In this report, we investigate to establish the method of evaluating the degradation state of sealant by gathering small samples. Concretely, we investigate whether assessing the degradation state of sealant is possible even by the chemical test besides the visual observation and the physical testing.
