“…This is due to the poor distribution of the fibers, which causes an increase in these samples' porosity. This performance was reported by Benaniba et al [19], Kenai et al [20], and Boumhaout et al [21] considered plaster and mineral paste reinforced with natural fibers.…”

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.

“…Zhou et al reported that kenaf fibers could decrease compressive strength by 12.2-46.2% although they increased the flexural strength by 30.7-66.9% [44]. Benaniba et al indicated that the flexural strength of date palm fiber reinforced concrete was increased at low fiber dosages, but the compressive strength was decreased at all considered dosages (0-30%) [45]. Overall, the compressive strength may be negatively affected by lignocellulosic fibers while the flexural strength can be still improved.…”

“…The hygrothermal behavior of concrete with 15 wt.% date palm fibers was studied at the wall scale, which showed that this material had very good hygrothermal performances and consequently could be used for thermal insulation and hygric regulation inside the buildings [58]. Also, increasing the date palm fiber content could increase the insulating capacity of mortar by reducing its thermal conductivity [45]. In addition, the treatment method of fibers affects the effectiveness of thermal insulation.…”

The lignocellulosic biomass wastes cause some burden on the environment; meanwhile, the concrete industry is faced with large amounts of carbon dioxide emissions and raw mineral materials consumption. The use of lignocellulosic biomass wastes in cementitious materials not only provides an alternative to deal with the wastes but also favors the sustainable development of concrete industry. This review first introduces the characteristics of lignocellulosic biomass and then examines its effect on the mechanical properties, shrinkage, cracking, and some other properties of cement composites. Results show that lignocellulosic biomass can be directly used for three purposes: reinforcements, aggregates, and cement replacements. Although the lignocellulosic biomass cannot always enhance the mechanical properties of cementitious materials, it can improve toughness, shrinkage, cracking, heat insulation, etc. Additionally, some concerns with the use of lignocellulosic biomass are summarized, for which some physical and chemical modification methods (heating treatment, boiling treatment, torrefaction treatment, etc.) are identified to change the structure or remove amorphous components of lignocellulose biomass or prevent it from directly contacting cementitious materials. This review can provide some guidance for designing sustainable cementitious materials with lignocellulosic biomass.

“…The main progress in the current building sector lies in the use of cellulosic nano-/micro-fibers/-fibrils extracted from diverse plant non-wood sources, including hemp, jute, flax, sisal, bamboo, bagasse, date-palm, etc., into composite materials of high-quality performance, service ability, durability, and reliability standards [18][19][20][21][22]. This strategy also plays a significant role in increasing the mechanical performance of mortars.…”

This paper aims to develop recycled fiber reinforced cement plaster mortar with a good workability of fresh mixture, and insulation, mechanical and adhesive properties of the final hardened product for indoor application. The effect of the incorporation of different portions of three types of cellulose fibers from waste paper recycling into cement mortar (cement/sand ratio of 1:3) on its properties of workability, as well as other physical and mechanical parameters, was studied. The waste paper fiber (WPF) samples were characterized by their different cellulose contents, degree of polymerization, and residues from paper-making. The cement to waste paper fiber mass ratios (C/WPF) ranged from 500:1 to 3:1, and significantly influenced the consistency, bulk density, thermal conductivity, water absorption behavior, and compressive and flexural strength of the fiber-cement mortars. The workability tests of the fiber-cement mortars containing less than 2% WPF achieved optimal properties corresponding to plastic mortars (140–200 mm). The development of dry bulk density and thermal conductivity values of 28-day hardened fiber-cement mortars was favorable with a declining C/WPF ratio, while increasing the fiber content in cement mortars led to a worsening of the water absorption behavior and a lower mechanical performance of the mortars. These key findings were related to a higher porosity and weaker adhesion of fibers and cement particles at the matrix-fiber interface. The adhesion ability of fiber-cement plastering mortar based on WPF samples with the highest cellulose content as a fine filler and two types of mixed hydraulic binder (cement with finely ground granulated blast furnace slag and natural limestone) on commonly used substrates, such as brick and aerated concrete blocks, was also investigated. The adhesive strength testing of these hardened fiber-cement plaster mortars on both substrates revealed lime-cement mortar to be more suitable for fine plaster. The different behavior of fiber-cement containing finely ground slag manifested in a greater depth of the plaster layer failure, crack formation, and in greater damage to the cohesion between the substrate and mortar for the observed time.
