Since the adhesion of reinforcement to concrete is the main factor of their joint operation, and the studies of fiber-glass composite bars with concrete are obviously insufficient despite the growth in their use in road and housing construction, an analysis was conducted to compare the adhesion between metal and fiber-glass reinforcement with heavy-weight concrete by the beam method. The adhesion forces create a complex stress–strain condition in the concrete adjacent to reinforcement bars. Such condition results in distribution of stresses along the reinforcement axis, so that the longitudinal forces on the reinforcement become variable along the entire bar length. It has been experimentally proven that as the stress on the concrete beam is increasing in the areas of contact between the reinforcement and concrete, shear stresses are observed to be shifting from the starting points towards the end ones within the anchoring area; and for metal reinforcement, the shear stresses are less than for glass composite. It has been determined that the adhesion stress between glass-fiber reinforcement and concrete is significantly higher than steel reinforcement.
