    Determining propertires of polyures coating as a material potentially strengthening structural elements
    (Wydawnictwo Politechniki Łódzkiej, 2022) Szafran, J.; Matusiak, A.
    The paper discusses the results of experimental research on polyurea. In authors’ opinion, this material could be used to improve load-carrying capacity and integrity of structural elements made of various materials. The paper presents the results of research on basic mechanical properties of polyurea, its impact on integrity of cellular concrete specimens and full-scale concrete rings. The additional polyurea layer on outer surfaces of test specimens improves mainly their integrity following their complete failure. It must be noted, however, that when the additional layer is present, it does not improve all strength properties of test specimens such as resistance to compression of cellular concrete specimens. It was revealed that this property may be negatively influenced by the level of constrainment.

    Polyurea Coatings as a Possible Structural Reinforcement System
    (Wydawnictwo Politechniki Łódzkiej, 2021) Szafran, J.; Matusiak, A.
    This paper describes studies completed under the research project “Polyurea coatings as a possible reinforcement system”. It primarily aims at assessing the usability of polyurea coatings for improving the performance of components of building structures. Basic studies on polyurea, simple physical tests and full-scale experiments were carried out for drawing up this paper. Their outcomes were analyzed, and the performance of the coating and its effect on building components was evaluated. The results of the analysis show that applying the polyurea coating makes it possible for structural elements to maintain integrity after their load-carrying capacities were exceeded, and helps improve other functional properties of a structure.
