ВЛАСТИВОСТІ ТА СКЛАД РЕМОНТНИХ СУМІШЕЙ ДЛЯ ВІДНОВЛЕННЯ МОСТІВ

The article provides a detailed review of modern repair mixtures used to restore bridge structures of various types. Particular attention is paid to the characteristics of the most popular materials, including polymer-cement, sulfate-resistant, mineral-reinforced and quick-hardening compositions. Their effectiveness under conditions of high loads, temperature changes, exposure to salts and chemically aggressive environments is analyzed. A comparative analysis is presented for key performance indicators: strength, frost resistance, water resistance, adhesion and durability. The application features, hardening time, adhesion to the substrate and behavior under prolonged mechanical stress are also taken into account. Based on the review, specific types of mixtures are recommended for individual bridge repair conditions, in particular emergency, planned and complex restoration measures. Illustrative materials, photographs and structural diagrams contribute to a deeper understanding of the effectiveness of each solution. The results of the study may be useful for design engineers, builders and technical specialists in the field of bridge construction and operation.
