“…Therefore, the increase in the porosity of the composite material as a result of the addition of fibers is the main factor responsible for the decrease in compressive strength. These results are in accordance with literature (Aruniit et al, 2011;Belkadi et al, 2018).…”

The development of eco-friendly composites as insulating materials in buildings offers practical solutions to reduce energy consumption, which is why scientists have started in recent decades to search for more sustainable and eco-friendly materials. It is well known that building materials are among the most commonly used materials and have an obvious negative impact on the environment. Therefore, this article presents a study on the use of a new bio-composite material, composed of natural fibers of date palm, cement, and sand. The objective of this study is to assess the thermal insulation properties, as well as the water absorption and mechanical performance of this material for the construction of buildings. The percentage by weight of date palm fiber in the test samples varied from 0% to 30% for a mixture of two fiber sizes equal to 3 mm and 7 mm. The characteristics of these samples were determined experimentally in terms of compressive strength, as well as thermal conductivity. The results show that the introduction of date palm fibers in mortars causes a decrease in compressive strength and thermal conductivity. This study affirmed that the use of vegetable fibers in cementitious composites has a positive effect on the properties of insulations and on the costs.

“…The test methods for resistance of CFCCs to chloride penetration adopt the rapid chloride 3 International Journal of Polymer Science migration (RCM) coefficient test and coulomb electric flux test. The procedures for preparing CFCCs reported in the literature can be divided into two main groups depending on the fiber form: fibers randomly dispersed in the cement matrix [58][59][60] and aligned fibers or fibrous structures [43,46,50,53]. In view of the fibers randomly dispersed in the matrix, it has certain limitations in the mechanical properties of reinforced composites, and aligned fibers or fibrous structures are also used to strengthen the cement matrix [49,56,57,61].…”

The performance of cellulose fiber-reinforced cement-based composites (CFCCs) depends not only on the characteristics of the cement matrix and fibers but also on the bonding property of the matrix and fibers. The durability of cement-based composites including various properties such as impermeability, frost resistance, and carbonization resistance has an important impact on the long-term service life of the matrix structure. The presence of a large number of hydroxyl groups on the molecular chain of cellulose can promote the formation of intra- and intermolecular hydrogen bonds of cellulose. This special structure imparts the cellulose high hydrophilicity, which leads the cement hydration C-S-H gel to adhere to the surface of cellulosic fibers (CFs) and induce its growth. The cavity of CFs has good water absorption and can be used as an internal curing fiber for the continuous hydration of cement-based composites. But CFs in the Portland cement matrix tend to deteriorate under strong alkali conditions. This paper presents a review of the research on the durability of CFCCs. The methods and paths to improve the durability of CFCCs are summarized and analyzed from the perspectives of the internal curing of CFs, the deterioration of the performance of CFs in the matrix, and the use of many types of supplementary cementitious materials. Finally, the development and engineering application of CFCCs have been prospected.

“…Belkadi et al and Merzoud et al evaluated the properties and performance of self-compacting concrete and cementing composite reinforced with fibers from Ampelodesmos mauritanicus, Alfa and date palm. They demonstrate an increase in adsorption of water of concrete, but a reducing of strength to compressive and flexural for composites reinforced with Ampelodesmos mauritanicus compared to the other plants (Belkadi et al;Merzoud and Habita, 2008). Ampelodesmos mauritanicus fibers were incorporated in polyester matrix up to 30% and a clear improvement in the mechanical proprieties of composite (tensile strength and Young's modulus) was achieved (Mustapha et al, 2016).…”
