Influence of curing, post-curing and testing temperatures on mechanical properties of a structural adhesive

• T g of the epoxy adhesive increased when was cured or post-cured at 50 °C. The increase in testing temperature produced a decrease mechanical properties. Compressive strength differently affected if curing below beyond . Tensile non-monotonic way for temperatures 20 Structural cold-curing adhesives are widely used to strengthen Reinforced Concrete (RC) structures with Fibre Polymers (FRPs). performance these adhesives, and therefore strengthening system, may be by temperature, as ambient-cured structural usually have low glass transition ( ). This paper presents comprehensive experimental investigation on influence properties adhesive. program divided four groups specimens. In Group 1, effect post-curing investigated. Groups 2–4, effects respectively, were studied. Experimental results confirm that depending whether applied Similar behavior observed epoxy, they showed improvements process (curing post-curing) negatively Besides, tensile compressive
