【 摘 要 】

This paper presents analysis of experimental data on increase of crack formation of reinforced concrete flexural members through deposition of protective polymer-cement coating improving the durability of civil structures in hostile environmental conditions. Polymer-cement coating is a composite based on low-molecular poly-butadiene as filling material with Portland cement. As a result of the research, we have obtained the data on load-carrying capacity of the members, relative level of crack formation and growth of deflection with load increment, depending on the thickness of covering layer, along with different strength of concrete in reinforced concrete flexural members. Research results will enable us to design civil structures withstanding various hostile environmental conditions owing to universal chemical stability of the coating, its high adhesion to different surfaces, including the concrete, thus ensuring preservation of performance characteristics of proposed structure, up to its destruction.
