The Effect of environmental factors on the adhesion of epoxy adhesives to concrete has been investigated. The results indicate that freezing and thawing up to 30 cycles and chemical environments such as sodium hydroxide and hydrochloric acid at different concentration do not have a significant effect on the effectiveness of the adhesion, regardless of epoxy formulations and bond thickness of epoxy adhesives to concrete. However, the cohesive strength of concrete is decreased by the effect of these environments. The load-bearing capacity of epoxy adhesives is diminished with increasing temperature. The reduction ratios vary with epoxy adhesive formulations and bond thickness. re epoxy adhesive formulations such as EP3 and EP4 with glass transition temperature values higher than the other epoxy systems offer substantial strength advantages at temperatures up to 80 degreesC.
