Investigation into the influence of vinyl polyester fibers on the basic properties of cement composites

92--99

The purpose of this study was to evaluate the effect of vinyl-polyester waste fibers on the properties of fresh and hardened cement mortars. Mortars containing 1%, 2% and 4% fibers of different fractions were analyzed. The results showed that the addition of up to 1% does not significantly affect mortar parameters, while higher dosage causes deterioration. These fibers may be a useful component of mortars in the context of recycling waste materials and reducing the environmental impact of construction.

W artykule zaprezentowano wpływ włókien winylowo-poliestrowych pochodzących z odpadów na właściwości świeżych i stwardniałych zapraw cementowych. Analizie poddano zaprawy zawierające 1, 2 i 4% włókien o różnej frakcji. Wyniki wykazały, że dodatek do 1% nie wpływa istotnie na parametry zaprawy, natomiast większe dozowanie powoduje ich pogorszenie. Badane włókna mogą stanowić użyteczny składnik zapraw w kontekście recyklingu materiałów odpadowych i ograniczania wpływu budownictwa na środowisko.

Recycled polymer fibers in cement composites for sustainable construction

Vol. 73, nr 5

art. no. e155031

Innovative approaches in urban development should address all aspects, including waste management, with a strong focus on sustainability and environmental protection. Various cementitious composites can be considered a viable medium that allows waste storage. In this study, the effect of the polyester-vinyl fiber addition on the strength and microstructural properties of cement mortars was investigated to determine the optimal fiber content. The fibers were added to the composite at 1%, 2% and 4% by weight of the cement mortar mix. The fibers used were fine fraction (0–1 mm) and coarse fraction (1–4 mm). The material microstructures, particularly in relation to the properties of the fiber-cement matrix interface for the selected mortar, were then characterized using scanning electron microscopy (SEM). The results showed that, aside from the reference sample, the mortars containing 1% fibers of both the fine and coarse fractions had the highest compressive strength. In relation to the reference mix, the sample with 2% fine fraction polyester-vinyl fibers and the sample with 1% coarse fraction fibers achieved the best flexural strength, lower than the reference sample only by about 4%. The worst performance in each test was achieved by mortars containing 4% fibers. The analysis conducted was compared with findings from related studies, indicating the possibility of solving the challenges observed during the research. The solution indicated in the paper has the potential to create a procedure for the disposal of used posters and banners in cement mortar production.
