The purpose of this study is to find appropriate polymer-modified repair mortars for polymer lining process in deteriorated sewage treatment structure. The polymer-modified repair mortars are prepared with polymer-binder ratio of 0%, 10%, and 20%; ground-granulated blast-furnace slag (BFS) contents of 0%, 25%, and 50%; fly ash (FA) contents of 0%, 10%, and 20%; and an antifoamer content of 3% and tested for strengths, adhesion, drying shrinkage, and sulfate resistance. It is concluded from the test results that the redispersible polymer powder (RPP)-modified repair mortars with BFA and FA cause improvements in its sulfate resistance, depending on the polymer-binder ratio. The properties of the RPP-modified mortars are satisfied with the KS (Korean Standard) F 4042 quality requirements. However, the RPP-modified repair mortars using BFS and FA require its improvement in strength.
