40 The research carried out in this study presents the effectiveness of using sodium acetate as a protective 41 material for concrete pavement. A newly developed freeze-thaw method that depends on the alteration 42 of temperature and humidity is introduced in this research to investigate the efficacy of integrating 43 sodium acetate with concrete with different water to cement ratios (w/c). Results from the introduced 44 freeze-thaw method were compared with the outcomes of a standard

... w testing method. The 45 distressed concrete was tested for water absorption and compressive strength after finishing six months 46 of freeze-thaw testing. Additionally, the morphology of sodium acetate and its interaction with concrete 47 were investigated by using Scanning Electron Microscope (SEM). Results demonstrated the 48 effectiveness of sodium acetate in protecting concrete. 49 50
