Fibre-reinforced polymer (FRP) reinforcement, with its positive attributes in regard to low required concrete cover, high tensile strength, light weight and high corrosion resistance, has become a vital part of the search for more resource-efficient and durable concrete constructions. In order to evaluate the construction material as a whole, not only the mechanical characteristics but also the environmental footprint has to be considered. We did just that and compared carbon, basalt and glass FRP to regular steel reinforcement. The assessment on a structural level proves an environmental potential when using the new materials for chosen construction elements!
