“…Gonilho-Pereira et al ( 2013) stated that despite the impact of waste fibre content on the evaluated mechanical parameters in cement-based mortars does not show a consistent trend, the use of 0.25% waste fibres (cotton and synthetic component) has improved the flexural and compressive strengths. When the literature is examined, the deterioration of compressive strengths of fibrereinforced cementitious products is attributed to the porous structure that arises due to increased fibre-matrix incompatibility and worsened workability along with the addition of fibres (de Azevedo et al, 2021;De Azevedo et al, 2020;dos Santos Alberton et al, 2023;Safiuddin et al, 2021). On the other hand, as shown in Figure 6, in this study, it has been determined that the fibre-cement matrix interface is highly dense and void-free, and the fibre-matrix compatibility is also found to be quite high.…”

The aim of this study was to investigate the utilization of recycled denim waste fibers (DWF) for reinforcing cementitious lightweight composite mortar (CLCM). The research focused on evaluating how the addition of DWF affected various aspects of CLCMs, such as flowability, fresh and hardened unit weight, porosity, water absorption, flexural strength, compressive strength, and load-deformation characteristics. Different proportions of fibers (0, 0.25, 0.50, 0.75, 1.00, 1.25, and 1.50 wt.% of cement) were incorporated into the CLCM. The results of the tests indicated a slight decrease in both fresh and hardened unit weights compared to the reference specimen. It was noted that the consistency of the mortars declined with the increasing addition of fibers. Additionally, the inclusion of any amount of fiber led to an enhancement in the mechanical properties of the lightweight mortars. Furthermore, the reference mortar exhibited less deformation under load, indicating its higher brittleness. Moreover, the study observed that the incorporation of DWFs had the ability to simultaneously improve both the ultimate load-bearing capacity and deformation of the mortars.
