“…The decrease in density is attributed on the one hand to the low density of the fiber compared to ordinary sand and on the other hand to the air voids trapped in the matrix by the introduction of the fibers during mixing [17]. The results obtained are consistent with those found by Sellami et al [14], Merzoud [11] and Achour et al [15].…”

“…Other work undertaken by Merzoud [11] on Diss fiber composites gave higher strengths; this confirms that the fibers play the role of reinforcement. The fibers have the main role of taking up the stresses and increasing the ductility of the composite, and also control the crack propagation and delay the final failure of the material by dissipating the excess energy.…”

This study investigates the potential use of Diss fibers as a sustainable alternative in ecoconstruction and civil engineering. The research introduced Diss fibers as aggregates, partially replacing conventional sand in mortar by volume with proportions of 1/3 and 2/3, aiming to create an eco-friendly and lighter mortar. In this context, various properties of the fresh mortars, such as density, workability, and occluded air content, were examined. Additionally, the mechanical performance in the hardened state, including compressive and flexural strengths, was evaluated. Durability parameters such as water absorption, capillary absorption, and resistance to aggressive media were also assessed. The results demonstrated that mortars incorporating Diss fibers were lighter and more workable. The inclusion of these fibers enhanced the flexural strength and chemical resistance, as evidenced by the low percentages of mass loss in aggressive solutions such as HCl and CH3COOH. However, the introduction of the fibers negatively influenced the mechanical resistance and water absorption-both by immersion and capillaritydue to the porosity introduced into the composites.

Clay is a raw material commonly used for the construction of building materials, thanks to the different stabilization techniques used. These claybased materials have very improved properties when they contain potashtreated vegetable fillers. Thus, coconut fibers, agricultural waste from wad treatment, coconut palm fruit wrap (Cocos nucifra) and treated with a potassium hydroxide solution were used for making clay materials and stabilized with cement. Its objective is to study the influence of these fibers on the properties of the material. To achieve this objective, mortars composed of clays stabilized with 8 % cement and fibers at different levels (0.2, 0.4, 0.6 and 0.8%) for a constant length of 30 mm, been developed. These different mortars with those containing no fibers were subjected to flexural and compression tests. The results obtained show that the addition of fibers improves the mechanical performance of clay mortars stabilized with 8% cement. Especially when these fibers are treated with solution of potash. The treatment of coconut fibers with the traditional potash solution made it possible to increase the maximum stress of the fiber mortar by 13% and by 5% their stiffness compared with untreated fibers. The fiber-matrix adhesion becomes stronger with fiber treatment by 8% by weight of potash.

The structure, anatomical characteristics and thermal properties of the plant ampledosmos mauriatnicus were analyzed. The analysis of mineral compounds was carried out by X-ray fluorescence (FRX). Physical properties were investigated by Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction and Thermogravimetric analysis (TGA). Scanning electron microscopy (SEM) was used to investigate the structure and morphology of sample. The results reveal the % (W/W) cellulose content of Diss is 28.13 %, hemicelluloses content is 26.26% and lignin content is 24.95 %. Analysis of extractives contents in Diss were revealed to be 12.03 %.According to XRD data, Diss showed, a crystallinity index (CI) 52.5 %. High crystallinity of cellulose induces thermal decomposition of fibers at high temperatures. These results show that this plant is rich in cellulosic fibers and that could be used as raw material in industries and paper making.In recent years, more attention has been given to lignocellulosic biomass for sustainable development and environmental preservation [1][2][3]. Studies focusing on lignocellulosic biomass are increasingly important in view of the various applications [4][5][6][7].The main biomass compounds are cellulose; hemicellulose and lignin. Hemicelluloses and cellulose are polysaccharides. Lignin is made of phenolic polymers that consist of three types of phenylpropaneuntis: p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol [8][9][10]. Cellulose is a polymer of beta-D-glucopyranose moieties linked via beta-glycosidic bonds [11,12]. The cellulosic chains have a variable degree of polymerization between 10000 units of glucopyranose in wood to 15000 units in native cotton [13][14][15]. The properties of cellulose depend on several parameters such as chain length, crystallinity, hydrogen bonds and the distribution of functional groups [8-16-18]. These important parameters make cellulose a unique material. Therefore, one of the most important sources of cellulose remains wood, however the use of annual plants can be used. Increasingly, annual plants are being used as a potential source for industrial processing. These plants are interesting because of their abundance and low cost and their main advantage is their rapid growth which makes them available in many regions of the world [19][20][21]. Annual plants, Diss (Ampelodesmos mauritanicus), can be also used as an alternative to wood for cellulose-based materials. This plant species belongs to the poaceae, is found in the Mediterranean and resists drought well [22][23][24][25][26]. To appreciate the potential of this plant, a physical, chemical, structural and thermal characterization is necessary. The aim of
