Abstract

Purpose. The purpose of this study is to assess the feasibility of using fiberglass strips manufactured with technology for reinforcing architectural decorative products made of natural stone by comparing their strength properties and behavior under bending strength. Methodology. The preparation of samples for strength testing has been carried out, and recommendations regarding the process have been described. Recommendations have been provided regarding the preparation, configuration, and implementation of the main tools and materials involved in the course of the research. Components of the experiment aimed at determining the strength characteristics of the samples have been developed and described. In accordance with the set tasks and the array of data obtained empirically, numerical values of the strength characteristics of natural stone products under external loads have been calculated. The calculations are performed in accordance with the general principles of theoretical and applied mechanics. Results. The influence of reinforcement on the strength of stone has been studied, expanding existing theoretical knowledge about the strength properties of stone and the possibilities for their improvement. New theoretical models and methods for assessing the strength characteristics of stone, taking into account the influence of reinforcing elements, have been developed, contributing to a deeper understanding of the processes occurring in the structure of stone during reinforcement. Scientific novelty. The existing methods of reinforcing natural stone products have been systematized and reviewed, and the ways to optimize them using modern composite material manufactured with fiberglass technology have been suggested. The feasibility of applying internal reinforcement technology to enhance the strength properties of natural stone products has been substantiated. For the first time, the methodology and effectiveness of applying internal reinforcement manufactured with fiberglass technology to improve the strength properties of products from the Pokostiv deposit granodiorite have been analyzed. Practical significance. The practical importance of the obtained results lies in the opportunity to transform theoretical knowledge into practical recommendations for improving the technology of manufacturing products from natural stone to enhance their reliability in operation and simplify the manufacturing process.
