Non-metallic fiber reinforced polymer (FRP) reinforcement bars can be a reasonable alternative to the traditional steel reinforcement. Basalt fiber reinforced polymer (BFRP) is considered as a novel reinforcing material. Aim of the project is to investigate the bond behaviour of BFRP with the surrounding concrete. First indications on the bond behaviour could be retrieved from an analysis of the microcrack distribution in the area close to the reinforcement, in bone shaped test specimen that had been subjected to a tensile load, as well as beams that had not been subjected to any load, in which the novel BFRP reinforcement was compared to conventional steel reinforcement. In both steel and BFRP-reinforced specimens, the bond zone between reinforcement and concrete appears to be the area with the highest number of microcracks. In addition, microcracks always seemed to grow in number and dimension with an increasing load, whereas in the BFRP reinforced specimens mainly more microcracks developed and in the steel reinforced specimen the microcracks mostly gained length and width.
