A Study on the Bond Between Basalt Composite Reinforcement and Concrete

<p>Based on experimental and theoretical research, the stress-deformation state of the bond between Georgian-origin basalt composite reinforcement and concrete was studied. The bonding mechanism between basalt composite reinforcement and different classes of concrete was revealed, along with the stress-deformation state of structures reinforced with basalt composite reinforcement. The bond strength (stress) between concrete and reinforcement was determined, which, at the moment of failure, exceeded the cohesive strength of concrete in the boundary zone. The effectiveness of concrete structures reinforced with Georgian basalt composite reinforcement was also recorded. The results of the experimental-theoretical research will be applied in the calculations of real concrete structures, taking into account the bond stresses between basalt reinforcement and concrete. An empirical formula was derived for calculating the anchorage length of basalt-plastic reinforcement in concrete.</p>
