Abstrakt: | An effective way to increase the resistance of reinforced concrete structures to the action of aggressive environments is the use of polymer composite reinforcement, in particular, glass composite reinforcement. In the scientific and technical literature, there are practically no data on the effect of the diameter and topography of the lateral surface of the glass composite reinforcement on its operational properties. The purpose of the work is to establish the influence of the diameter and topography of the lateral surface on the strength of the glass composite reinforcement. As an object of research, composite reinforcement with a diameter of 6-24 mm, manufactured by Ruscompozit (Russia), was used. The strength characteristics were determined in accordance with current standards on modern testing equipment. It is shown that with an increase in the diameter of the glass composite reinforcement, the density increases and the physical and mechanical characteristics of the reinforcement decrease. At the same time, composite reinforcement with sand coating has a higher strength compared to the glass composite reinforcement with a spiral winding. It has been established that with an increase in the ambient temperature from -60 °C to +60 °C, the strength of the glass composite reinforcement decreases. It was revealed that the chemical resistance of the glass composite reinforcement depends on the chemical nature of the aggressive environment and, to a lesser extent, on its diameter. Data on the resistance of glass composite reinforcement with sand coating and with spiral winding in an alkaline environment are given. [ABSTRACT FROM AUTHOR] |
