Abstract
Underground concrete structures are constructed under a geographical environment called underground and exposedto various environments that promote deterioration. Among them, groundwater promotes deterioration of undergroundconcrete structures due to contaminated water from the ground. In this study, the chemical resistance performance testevaluation of five different receptors for a total of 15-type leakage repair materials of five series was conducted todetermine the chemical stability of the leakage repair material used in the crack area. The results show a generalincrease and decrease in most chemical receptors, but the biggest increase and decrease was shown in acrylic systems,which were found in sodium chloride and sodium hydroxide, and epoxy was found in hydrochloric acid. The cementsystem is showing a lot of increase and decrease in sodium chloride. It is expected that the results of these studieswill be used as a basis for chemical stabilization in the development of new materials.
