Impact ballistic resistance of high workability concrete reinforced with crushed wind-turbine blade

Abstract

The implementation of circular economy in the wind-energy sector can be promoted by recycling the dismantled wind-turbine blades through crushing to produce fibres. The use of those fibres in self-compacting concrete allows improving its ductility and energy absorption, behavior that is analysed in this research by evaluating its impact ballistic resistance. The addition of this waste fibres from a percentage of 4.5% increased the flexural strength and impact ballistic of concrete. Although concrete with those recycled fibres did not reach the performance of conventional concrete, this study meant a starting point to try to develop concrete with that waste that exhibits high resistance to such external stresses
