Investigation of the dependence of the adhesion value on the profile type of composite rods under the condition of reinforcement of stone products

Abstract

The main task that is being solved in the course of writing this article is to establish experimentally the dependence of the value of the adhesion value on the type of profile of composite rods, provided that they are used for reinforcing stone products. Within the framework of the work, the expediency of using composite reinforcement with indented, spirally glued (at an angle of 35° and 80°) and sand-coated profiles and their ability to interact with epoxy binders is considered. Based on the results of the experiment, the ability of each of the types of profiles under study to resist pulling out of the stone sample was established (at the same time, a steel rod with a periodic profile was used as a reference for which all other samples were compared). According to the results of comparison of the obtained results for reinforcement of structures that will be operated under the influence of bending or breaking loads, including for complex products, the connection of which is provided by the use of reinforcing rods, the best option among the compared will be rods, the surface of which is covered with a sand mixture.
