Abstract (EN): A comparative study of the influence of thermal effects on flexural strength of two different binder formulations of polymer mortars was performed. For this purpose, specimens of unsaturated polyester and epoxy polymer mortars were exposed to a large range of temperatures, between -20 and +100 degreesC, and tested afterwards in bending. For each temperature level, flexural strengths at test temperature, and residual flexural strengths after temper, were determined. The strength degradation process occurring in the material, as a consequence of positive thermal fatigue cycles (+20 degreesC/+100 degreesC) and freeze-thaw cycles (-10 degreesC/+10 degreesC), was also quantified and analysed. Obtained results show the relevance of material properties assessment with temperature.
