Effect of temperature on systems for the reinforcement of concrete

This paper presents an experimental work using prismatic specimens of hydraulic mortar reinforced on the exterior with steel or CFRP plates. The adhesive used was an epoxy. Two series of tests were made. In the first one, the specimens were exposed seven days to temperatures between 20 ºC and 250 ºC, after which they were subjected to flexure tests made at 20 ºC. In the second series, the specimens were exposed...

Effect of temperature on the rupture of systems for the reinforcement of concrete

The adhesives used in systems for the external reinforcement of concrete are epoxies. Like all the polymers, they have low thermal resistance. This paper presents the results of an experimental work made with specimens of hydraulic mortar reinforced on the exterior with steel or CFRP plates. The specimens were exposed seven days, to temperatures between 20 and 250 ºC. To determine the adhesion, we used flexure ...
