Tekstil Açma İşlemi Atik Liflerinin Betonun Fiziksel Ve Mekanik Özelliklerine Etkisinin İncelenmesi

Abstract

In this study, the effects of incorporating textile shredding process waste fibers into fiber reinforced concretes were experimentally investigated. A total of six concrete mixtures with varying fiber contents (0 to 3.6 kg/m3) were produced and examined in terms of physical and mechanical properties. The results showed that the addition of up to 1.2 kg/m3 fibers improved the hardened density of the mortars due to enhanced compactness and void filling. However, further increases in fiber content led to reductions in density and workability, as indicated by decreased slump values. Despite this, compressive and flexural strength values increased with fiber addition up to certain thresholds, particularly at early curing ages (7 and 28 days). The highest increase in compressive strength at 28 days was recorded as 13.79% compared to the reference sample. A slight decrease in long-term compressive strength (150 days) was observed at higher fiber contents, likely due to fiber degradation in prolonged water exposure. These findings suggest that waste fibers can enhance the early-age mechanical performance of lightweight mortars, offering a sustainable and effective approach to fiber reinforcement in cement composites. However, optimal dosage and curing strategies must be considered to ensure long-term durability.
