Analysis of Material Performance According to the Cooling Method of Fire Damaged Concrete

Abstract

In this study, material performance was analyzed depending on the cooling method of concrete damaged by fire. Various non-destructive and destructive tests were conducted for material performance analysis. Further, the influence of cooling methods was assessed according to each test. As a result of the evaluation, it was confirmed that the residual performance of the concrete was significantly different according to the cooling method (air cooling and water cooling), and the performance difference according to the cooling method was also observed depending on the exposure temperature. Through this study, it was possible to understand the impact of water used in firefighting on fire-damaged RC structures, and it is deemed necessary to further study various concrete mixing models.
