| Title of the article | The research of short-term and long-term strength of adhesives bond joint for the external reinforcement of building structures |
| Abstract. | Problem statement. Use of external reinforcement systems using carbon composite materials is one of the most effective modern methods of strengthening building structures. It is necessary to know the durability or predicted service life of polymer composite materials to assess the technical and economic efficiency of external reinforcement in building structures. The purpose of this stage of work is to determine the long-term durability coefficients of adhesive joints based on the results of mechanical tests. Results. The adhesion strength of adhesive joints was investigated in such compounds as: «metal-glue-metal», «concrete-glue-textiles», «metal-glue-textiles». The values of short-term and long-term strength of adhesive joints of various types were determined, obtained temperature coefficients of working conditions for different temperature operation conditions, calculated the coefficients of long-term strength. Conclusions. The significance of the obtained data for the construction industry consists in the development of methods for assessing the durability of adhesives for the construction of external reinforcement systems. The results obtained at this stage will be used in conducting experimental work to assess the durability of epoxy adhesives and predict the service life of external reinforcement systems for building structures. |
