Abstract
The paper analyzes advantages and disadvantages of composite reinforcement while reinforcing concrete structures. Results of experimental investigations on adhesion strength of fiberglass reinforcement manufactured in the Republic of Belarus with concrete have been given in the paper. The paper contains an analysis pertaining to the influence of concrete contact diameter and length of fiberglass reinforcing bars on strength and deformability of adhesion with concrete. Failure behavior of prototypes and maximum loading that does cause breakage in adhesion of fiberglass reinforcement with the concrete have been controlled in order to study the influence of diameter and length of fiberglass reinforcing bar contact with the concrete on strength and deformability of concrete adhesion for composite reinforcement produced by various manufacturers. Displacement of non-loaded (free) and loaded ends of the reinforcing bars with regard to concrete exposed face on both specimen ends has been also controlled. The experiments have shown that destruction of the prototypes occurred due to initiation of one of the following three reasons: reinforcement sliding in reference to concrete, cleaving of a protective concrete layer or breakage of composite reinforcement. Start-up moments for reinforcing bar slip in relation to the concrete have been determined with the help of two methods. The paper provides proposals for calculation assessment of anchorage in the concrete for fiberglass reinforcement manufactured by the following enterprises and companies “Stroykompozit” (Gomel, Republic of Belarus), Research and Production Company (RPC) “Biznes-Kontinent” (Brest, Republic of Belarus) and Private Eenterprise (PE) “Minplast” (Minsk, Republic of Belarus).
