“…This treatment not only reinforced the mechanical properties of the fibers but also optimized their bonding strength with the fiber-matrix interface. The specific treatment conditions were established based on insights from recent studies [16,17]. In this process, initially cleaned fibers were immersed in a 1% NaOH solution at 100°C for a duration of one hour.…”

Abstract. In Morocco, the prevalent use of building materials with low thermal resistance has translated into substantial energy consumption. This has underscored the pressing need to promote the development and adoption of sustainable construction and insulation materials. The primary objective of our study is to enhance the thermal properties of plaster by incorporating date palm fibers (DPF) to create an exterior wall coating. To evaluate the thermal properties of the resulting Gypsum-DPF bio-composite material, we conducted several experimental measurements of thermophysical properties. These measurements encompassed the determination of bulk density and thermal conductivity, which were assessed using the steady-state hot plate method. Our findings reveal that the inclusion of date palm fiber in the material led to a noteworthy reduction in bulk density, amounting to approximately 17.16%. Furthermore, thermal conductivity decreased by approximately 26.24%. These outcomes underscore the potential and value of utilizing this bio-composite material in building construction to enhance thermal comfort and, critically, contribute to a reduction in greenhouse gas emissions, particularly CO2 emissions.

“…Basha et al (2020) have indicated that raising the amount of RPA in self-compacting concrete can result in a reduction in its compressive strength, this is a consequence of the debonding between RPA and the mortar matrix. Moreover, RPA is more prone to absorbing water, which increases the porosity of the concrete (Rachedi, 2018), and this can lead to a decrease in the strength of the concrete. The same can be seen in Figure 8(a), which shows the inverse correlation between RPA and CS.…”

Self-compacting concrete (SCC) is a type of concrete that is known for its environmental benefits and improved workability. In this study, data-driven approaches were used to anticipate the compressive strength (CS) of self-compacting concrete (SCC) containing recycled plastic aggregates (RPA). A database of 400 experimental data sets was used to assess the capabilities of Multi-Objective Genetic Algorithm Evolutionary Polynomial Regression (MOGA-EPR) and Gene Expression Programming (GEP). The results of the analysis indicated that the proposed equations provided more accurate CS predictions than traditional approaches such as the Linear Regression model (LRM). The proposed equations achieved lower mean absolute error (MAE) and root mean square error (RMSE) values, a mean close to the optimum value (1.0), and a higher coefficient of determination (R2) than the LRM. As such, the proposed approaches can be utilized to obtain more reliable design calculations and better predictions of CS in SCC incorporating RPA.

“…This treatment improves the mechanical properties of the fibers and adjusts the adhesion strength of the fiber-matrix interface. The conditions for the treatment of fibers are based on the results of recent studies [15,16]. Firstly, the pre-prepared clean fibers were soaked in 1% concentration NaOH solution at 100°C for 1 h and then washed with water to remove the excess of NaOH sticking to the surface of the fibers, after that it bleached with sodium chloride, finally the fibers were washed again thoroughly with water and dried in the room temperature for 24 h before use.…”

The negative impact of the production and use of building materials on the environment has become evident, so in recent decades, to find more sustainable, eco-friendly, and low-cost materials, the last research tends to reconsider the use of natural fibers and traditional building materials. This paper aims to develop a bio-composite based on the southern Algerian region's local materials consisting mainly of plaster and waste from date palm trees. Many properties were examined experimentally through previous research of our team (physical, mechanical, and microstructure characteristics) [1, 2] to characterize these materials. Several samples of bio-composite of plaster configurations with short length (20mm) and eight-weight ratios (0.5% - 4%) of palm fibers were prepared for mechanical, thermal, and physical characterizations. In addition, tested all previous properties on the specimens after 28 days of curing in normal conditions. The results show a clear improvement in the bio-composites mechanical performance (an increase in the bending strength with achieving compressive strength) and their thermal properties, which have been well developed (density, thermal conductivity, and specific heat capacity). To enhance the resistance of palm fibers to chemical degradation in the plaster's alkaline environment and improve the adhesion between them, these fibers were treated with a NaOH solution of 1% concentration. The plaster's composites reinforced with date palm fibers can be qualified as eco-friendly and thermal insulation building materials.
