“…The boiling treatment can remove some water-soluble substances, accountable for setting delay and incompatibility problems with the matrix, and clean the surface of lignocellulosic biomass [85]. Ali-Boucetta et al reported that the setting time for the nonfiber mixture increased from 4 h 10 min to 5 h 30 min if raw date palm fibers were involved; however, compared to untreated fibers, the water boiling treated fibers reduced the delaying time by 15%-33%, proportional to the boiling time [86]. The main reason may be attributed to the reduction of watersoluble sugars, which is confirmed by Sellami et al who found that the amounts of water-soluble sugars for untreated Diss, boiled-but-not-washed Diss, and boiled-and-washed Diss were 30.78%, 1.95%, and 0.72%, respectively [87].…”

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.

“…Chemical treatment can be acetylation, silane treatment, and mercerization [ 103 ]. Several studies demonstrate the use of chemical surface treatments on cellulosic fibers to reduce their hydrophilic character and improve their adhesion properties with the matrix [ 104 , 105 , 106 ]. Most works with lignocellulosic fibers in cementitious matrices are based on treatments with alkaline solutions: Ca (OH) 2 , NaOH, KOH, LiOH, Na 2 CO 3 [ 14 , 53 , 97 , 106 , 107 , 108 , 109 ].…”

The use of natural lignocellulosic fibers has become popular all over the world, as they are abundant, low-cost materials that favor a series of technological properties when used in cementitious composites. Due to its climate and geographic characteristics, Brazil has an abundant variety of natural fibers that have great potential for use in civil construction. The objective of this work is to present the main concepts about lignocellulosic fibers in cementitious composites, highlighting the innovation and advances in this topic in relation to countries such as Brazil, which has a worldwide prominence in the production of natural fibers. For this, some common characteristics of lignocellulosic fibers will be observed, such as their source, their proportion of natural polymers (biological structure of the fiber), their density and other mechanical characteristics. This information is compared with the mechanical characteristics of synthetic fibers to analyze the performance of composites reinforced with both types of fibers. Despite being inferior in tensile and flexural strength, composites made from vegetable fibers have an advantage in relation to their low density. The interface between the fiber and the composite matrix is what will define the final characteristics of the composite material. Due to this, different fibers (reinforcement materials) were analyzed in the literature in order to observe their characteristics in cementitious composites. Finally, the different surface treatments through which the fibers undergo will determine the fiber–matrix interface and the final characteristics of the cementitious composite.

“…Many researchers have been investigating the feasibility of using date palm fibers (DPF) in cement-based materials [4][5][6][7][8][9][10][11][12][13][14][15][16]. They concluded that some properties of concrete and mortar could be improved.…”

“…Swelling, drying shrinkage, and chemical resistance to acidic solutions were investigated for mortar containing DPF [12], showing better performance than control mortar against shrinkage and acidic attacks. To improve the mechanical properties of reinforced DPF mortar, the DPFs are pretreated by different methods such as boiling in water, immersing in sodium and calcium hydroxide, and coating with oil [13][14][15]. Mortars containing treated DPF showed better mechanical properties than mortars containing untreated DPF fibers.…”

This paper presents the results of a study conducted to investigate the effects of incorporating Sefri Date Palm Leave Fibers (SDPLF) into the mortar. A total of seven mixtures were prepared and tested. SDPLF were collected from local farms. The fibers were then cleaned, dried, and cut to different sizes of 10 mm, 20 mm, and 50 mm, maintaining the same individual fiber width of approximately 5±2 mm. The content of SDPLF in mortars was kept to 1% and 3% by mass. The physical and mechanical properties of SDPLF fibers and SDPLF mortars were investigated. The compressive strength at 7, 14, and 28 days was determined. The water absorption rate test was carried out on mortars containing 1% SDPLF fibers. The results showed that mortars with SDPLF have lower workability, lower density, and lower compressive strength as compared to control mortars. However, they are still acceptable for use in construction works. Mortars containing 10 mm and 20 mm SDPLF fibers by mass showed significant improvement in terms of water absorption rate as compared to the control mortar.
