ABSTRACT
Some of the first-installed wind turbines will have to be replaced soon, as they are
approaching the end of their life span. These wind-turbine blades must be recycled,
so their suitability to be added into concrete mixes as fibers is studied. Thus, a less-
polluting fiber-reinforced concrete can be achieved, maintaining its mechanical
behavior. To recycle numerous wind-turbine blades at an adequate rate, large
amounts of waste need to be added into concrete. This study aims to find out the
suitability of adding high amounts of this waste material (0% vol., 5% vol., and
10% vol.). Testing yielded a slight decrease in fresh density and a higher occluded
air content, yet largely maintaining its suitability for structural use according to the
compressive strength. The results showed that concrete with a high content of
crushed wind-turbine blade is suitable for structural use, being it an effective
solution to said current sustainability problems.
