| dc.description.abstract | The study of the structure of cement systems, the formation of initial defects in it and the possibility of their detection at early stages to prevent further development has become an urgent issue now. Monitoring systems for the stress-strain state of concrete and reinforced concrete structures are also relevant. The creation of such systems would make it possible to register structural changes in a concrete structure, to assess the degree of this change, thereby preventing possible destruction of the object under study. The purpose of the thesis is to study the structure of cement systems, namely the formation and development of initial defects in it, the possibility of their detection at early stages. Creation of a system for monitoring the stress-strain state of cement composites. Creation of an effective tool that will allow continuous monitoring of the structural integrity of cement composites. The main results of the work: 1. Developed an experimental system for monitoring the stress-strain state of cement composites, based on the tensometry and acoustic emission methods; 2. Designed and tested a model of an internal strain gauge sensor (embedded sensor) for determining the structural changes of cement composites; 3. Created a 3D-package model of the studied cement composite for future research. | pt_PT |
