Abstract (EN): The need for cost-effective end-use applications for fiber reinforced thermoset polymer (FRP) wastes has led to a great amount of research work on recycling techniques and potential applications for the recyclates. Mechanical recycling has been considered the most mature recycling technique, but more feasible outlets for the recyclates should be identified. Extensive research works have been carried out on concrete composite materials, in which ground FRP scrap has been incorporated as reinforcement, aggregate, or filler replacement. As a function of mix design and recyclate sorting technique, reported added values comprise decrease of permeability, a less drying shrinkage and wear loss, and a global cost reduction of raw materials. However, these products have not yet been successfully reflected in the industry market mainly due to one or more of the following reasons: adverse effects of recyclate addition on mechanical properties, negative cost balance where recycling and refining operation costs outweighed the market value of virgin product, and lack of clear and developed routes between waste producers and potential consumers for the recyclates. This chapter is aimed at enclosing and summarizing an updated review regarding all these issues: recycling techniques of thermoset FRP wastes, FRP recyclatesmodified concrete materials, end-use applications, and market outlook. © 2017 Scrivener Publishing LLC.
