AbstractAbout AuthorsReferences
External reinforcement systems using carbon composite materials are one of the modern methods of strengthening building structures. As the results of existing scientific research show, the component most susceptible to external factors in these systems is an epoxy adhesive. In the present work, experimental studies have been carried out in order to obtain data for the development of a standard method for accelerated assessment of the durability of building structures reinforced with external reinforcement systems with polymer composites. The importance of influencing factors such as: UV radiation; temperature; moisture and alkaline solution on the aging rate of adhesives for external reinforcement systems has been revealed. A step stress method is proposed to predict the creep of the initial and aged adhesive samples.
