“…This is favorable to the fiber-matrix interface performance. In addition, the cellulose content may also increase because of the removal of remains components during hornification [94]. It is widely known that cellulose contributes the most to the mechanical properties of fibers, so the increase of cellulose content may improve the mechanical properties of hornificated fiber reinforced cement-based composites.…”

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.

This paper presents some principles of research done on the assessment of fiber-matrix adhesion and durability in cement-based and polymer-based composites reinforced with vegetable fibers. Natural vegetable fibers are light, biodegradable and low-cost; however, their compatibility with both matrices - which are generally hydrophobic- is poor, because of their hydrophilic character. This review presents the different strategies proposed in literature to improve (1) interfacial bonding between matrix and fibers and (2) sustainability of composite materials reinforced by vegetable fibers. In order to achieve these goals, searchers investigate chemical or/and physical treatments of fibers and/or matrix modification of composites materials. The impacts of these strategies are followed in terms of mechanical properties, thermal properties, morphology and water absorption of the composite materials. Authors proposed to focus on the influence of aging on these characteristics in order to estimate durability.
