FIELD EVALUATION OF EPOXY ADHESIVES UNDER EXTREME TEMPERATURE ENVIRONMENTS

摘要

Structural adhesives can offer substantial economic advantages for the construction industry. Recent advances in the adhesive science and technology suggest that structural adhesives have enormous potential in future construction and repair applications, particularly where the combination of thick bondlines, ambient temperature curing and the need to unite dissimilar materials with a relatively high strength and toughness capabilities are required. This paper presents the results of a pilot experimental study on evaluating the structural behavior of structural adhesives under extreme temperatures environment. The proposed method can be utilized at the site as an inspection and evaluation tool for structural adhesives properties, especially for applications related to concrete repair and rehabilitation. The paper presents experimental results describing the behavior of several adhesives tested in this study. All adhesives were tested under both ambient and extreme temperature conditions. Conclusions and discussions on the effect of extreme temperatures on the strength of the structural adhesives are presented.
