| Title of the article | The modulus of elasticity of epoxy adhesives used to strengthen reinforced concrete structures with external reinforcement systems. Part 1: The effect of changes in the modulus of elasticity on the stress-strain state of a concrete beam reinforced with an external reinforcement system |
| Abstract. | Problem statement. The component of external reinforcement systems that is most susceptible to the effects of operational factors is epoxy adhesive. The purpose of this work is to study the effect of changes in the elastic modulus of an epoxy adhesive on the creep of a reinforced structure. The objectives of the study are: the development of compositions of epoxy adhesives having regulated elastic modulus, conducting strength and creep tests. Results. The paper presents the results of stress-strain state studies of reinforced concrete beams reinforced with piles. According to the results of the study, it was revealed that a decrease in the elastic modulus of the adhesive leads to an increase in deformability and reduces the strength of reinforced beams. Conclusions. The significance of the results obtained for the construction industry consists in establishing the dependence of the stress-strain state on the physical and mechanical characteristics of adhesives used in strengthening building structures. These results can be used in the development of adhesives with specified characteristics for certain operating conditions. |
