This paper presents the results of an experimental investigation to study recycling-methods of Fiber-Reinforced Polymers (FRP), extracted from Wind-Turbines Blades into concrete. Chemical composition (non-organic), mineralogical analysis, organic content, pozzolanic activity were examined. The effects of adding waste wind-turbine blade FRP-material (WTB-FRP) into concrete as a partial replacement of cement and fiber reinforcement were studied under the uniaxial compression and 3-point bending load. According to the test results, the high wooden content caused significant increase in the setting time of cement paste (up to 4 days for 40% of cement replaced) and significant drop in compressive and flexural strength if added as powder due to the retardant properties of wood powder and its high water absorption. The concrete mixture tests for the fibers showed slight decrease in compressive strength (up to 4% for 1,25% of fibers by weight) and increase in flexural strength up to 15%. No deterioration of E-glass by high alkalinity of hydrated cement was observed due to the protective layer of polymer formed around the fibers.
