Wzmocnienie betonu za pomocą zbrojenia rozproszonego znacząco poprawia jego odporność na pękanie, skurcz oraz trwałość. Asortyment włókien komercyjnych jest szeroki, jednak ze względu na wysoki koszt produkcji wpływający na ostateczną cenę konstrukcji, sporadycznie wykorzystywany w praktyce. Stosowanie włókien z recyklingu pochodzących z komunalnych lub przemysłowych odpadów, oprócz niskiego kosztu, generuje dodatkowe zalety, takie jak redukcja ich ilości i oszczędność zasobów naturalnych. W artykule przeprowadzono przegląd badań nad wzmacnianiem betonu przy użyciu włókien z recyklingu (WFRC – Waste Fiber Reinforcement Concrete), obejmując materiały takie, jak wióry z tokarni, włókna z wykładzin dywanowych oraz odpady poprodukcyjne z bazaltu. Przedstawiono wpływ włókien na poprawę właściwości fizycznych i mechanicznych betonu. Na podstawie literatury wskazano zalecenia przygotowania matrycy betonowej i stosowania fibrobetonu (FRC) wzmacnianego różnorodnymi typami włókien odpadowych.

The amplification of concrete with distributed reinforcement significantly enhances its resistance to cracking, shrinkage, and durability. The range of commercial fibers is extensive; however, due to high production costs impacting the final price of the construction, they are rarely used in practice. The use of recycled fibers derived from municipal or industrial waste, besides their low cost, generates additional benefits such as waste reduction and natural resource savings. This article reviews research on the reinforcement of concrete using recycled fibers (WFRC – Waste Fiber Reinforcement Concrete), encompassing materials such as machine scrap, carpet fibers, and basalt production waste. The impact of fibers on the improvement of the physical and mechanical properties of concrete is presented. Based on the literature, recommendations for the preparation of the concrete matrix and the use of fiber-reinforced concrete (FRC) strengthened with various types of waste fibers are provided.
