| Abstract Scope |
The decommissioning of wind turbines in the coming decades highlights the need to establish a method for their recycling. Raw-Crushed Wind-Turbine Blade (RCWTB) is a material containing Glass Fiber-Reinforced Polymer (GFRP) composite, spherical balsa wood particles and polyurethane, obtained after non-selective cutting and crushing of wind turbine blades. In this research, the behaviour of five concrete mixtures with RCWTB global additions up to 6.0% by volume was evaluated under different mechanical and durability tests. The mechanical properties evaluated did not experience significant deterioration and some improvements were even observed due to the bridging effect of the fibers with the cementitious matrix. Regarding durability, it was observed that the higher the RCWTB content, the higher the water absorption rate of the concrete samples, which is the main way of aggressive agents’ entry. Despite this, the results obtained were in all cases indicative of good quality concrete. |
