“…Therefore, fibres play a crucial role in inhibiting crack propagation within the matrix, thereby preventing the brittle failure typically observed in fibreless cement matrices. Similar findings have been reported by Martins et al (2015), Zaid et al (2021) and Sellami et al (2022) in their investigations on soil-cement-sisal fibre composites, reinforced lime composites and diss fibre reinforced mortar, respectively.…”

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.

“…For instance, the utilization of sisal fibers, jute and diss shows promise in enhancing composites by providing cost savings, impressive robustness, and posing no health risks to humans. 20 In another study, Sellami et al 21 found that the addition of dissimilar fibers of Diss in different ratios (20%, 25% and 30%) to the bending samples of a cement matrix improved the behavior of the post-peak with increased deformation and rigidity. Adin et al 22 observed that the introduction of natural jute fibers as reinforcement in pure polypropylene composites led to improvements in both tensile and bending strength.…”

This study explores the relationship between natural fiber filling density (10%, 15%, 25%) and its impact on the bending properties of polymer compounds reinforced with Diss, Sisal and Luffa fibers. Using advanced techniques like fiber analysis and Fourier transform infrared spectrometry (FTIR), the research reveals that a 25% filling density results in the highest stress values (25.61 MPa, 22.21 MPa and 20.88 MPa) for Diss, Sisal and Luffa compounds, respectively, fostering robust bonds in Diss-reinforced polymers. The Artificial Neural Network (ANN) model demonstrates superior predictive capability with correlation coefficients exceeding 0.99 for stress and displacement, outperforming Response Surface Methodology (RSM). Analysis of Variance (ANOVA) underscores the impact of sample section parameters and fiber rate on stress, establishing the significance of type parameters and fiber rate on displacement. This integration of ANN and RSM represents a paradigm shift in predicting bending mechanical properties, advancing our understanding of composite materials for innovative applications.

“…Raw earth bricks reinforced with straw are an example. However, the transition from the traditional clay matrix to the cement matrix is relatively recent, yet plant fibers are locally available, renewable, less polluting [1][2][3][4][5][6][7] and require little energy for their transformation compared to synthetic fibers [8][9][10][11][12]. The reinforcement of mortars and concretes with fibers dates back to the beginning of the 19th century [13] and the use of vegetable fibers in these materials dates back to the seventies of the 19th century, when the first works aimed to replace asbestos fiber in the elements prefabricated [14].…”

“…In Algeria, studies on the use of plant fibers in concrete and mortar are recent. These works concerning vegetable fibers that are available in Algeria such Diss [1,[4][5][6][7], Alfa [7,[32][33][34] and date palm fibers [4,7,35,36]. The number of date palms of different species is estimated at 18 million feet in Algeria, cultivated over an area of 165,000 hectares [4,37], generating more than 200 tons of waste deposited in landfill or burned [4,36].…”

This article presents the results of a comparative experimental study on the influence of date palm fibers to replace polypropylene fibers used as reinforcement in self-compacting concrete (SCC). Indeed, the use of polypropylene fibers makes it possible to reduce the plastic shrinkage of concrete. Date palm fibers have mechanical characteristics (tensile strength and elasticity modulus) largely sufficient to replace polypropylene fibers. The use of natural fibers has several advantages, they are natural, renewable, have no affect the environment and require little energy for their transformation, unlike synthetic fibers. In this comparative study, polypropylene fiber is used as control material and date palm fiber as study material. The results obtained show that the two types of fibers decrease the fluidity and the compressive strength but increase the flexural strength and decrease the shrinkage. Date palm fibers delay the appearance of cracks more than polypropylene fibers. Date palm fibers guarantee the best results of SCCs in fresh and hardened state
