“…In the last years, the utilisation of lignocellulosic materials to process novel composites has attracted a growing interest. Such a success is explained by their low-cost and their environmentally friendly character [3]. Indeed, important industries, such as automotive, building and packaging, have focused their attention on the development of new materials filled with natural fibres or powdered particles.…”

“…The increasing demand for lignocellulosic materials for traditional uses (mainly paper and textile production, but also for cellulose derivatives) and their potential incorporation into new material families necessitates looking for new sources. For this purpose, several studies have tried to valorise various agricultural or industrial by-products available locally [3].…”

“…In addition to the above-mentioned advantages, these materials possess interesting mechanical and physical properties [14], which, however, vary according to their botanical origin. In fact, lignocellulosic fibres or particles are available mainly from wood, but several local annual plants and agricultural crops as well as industrial residues can also be considered as potential sources of raw materials [3]. During the last decade, several composites based on lignocellulosic materials from worldwide annual plants, such as Cannabis sativa, kenaf, eucalyptus, rice straw, bagasse and cotton have been studied [14].…”

-The paper presents application of cellulose fibres in a pulp form from waste paper to mortar or plaster. The pulp from waste paper substitutes a part of inorganic filler or binder in cementitious composites. The characterization of properties and use of mortar or plaster mixtures as well as wood pulp fibres used in cement-based materials is presented in the article. The results of testing the technically important parameters (density, water resistance, coefficient of thermal conductivity, tensile strength at bending) of composites which were obtained by compiling the available works are summarized.

“…Synthetic fibers contribute to formation of optimum mineral frame and decrease of shrinkage deformation in foamed concrete. According to foreign researchers [3,4], apart from the mentioned advantages the use of discontinuous fibers enables to reduce mass of a structure, improve thermal protection characteristics and fire resistance of wall structures.…”

Abstract. One of the promising means of foamed concrete quality improvement is micro-reinforcement by adding synthetic and mineral fibers to the base mix. This research is the first to investigate peculiarities of using recycled cellulose fiber extracted from waste paper for obtaining fiber reinforced foam concrete. The paper presents results of experimental research on the influence of cellulose fibers on structure and properties of fiber reinforced foam concrete by using methods of chemical analysis and scanning electron microscopy. The research determines peculiarities of new formations appearance and densification of binder hydration products in the contact zone between fiber and cement matrix, which boost mechanical strength of fiber reinforced foam concrete. Physico-mechanical properties of fiber reinforced foam concrete were defined depending on the amount of recycled cellulose fiber added to the base mix. It was found that the use of recycled cellulose fibers allows obtaining structural thermal insulating fiber reinforced foam concretes of non-autoclaved hardening of brand D600 with regard to mean density with the following improved properties: compressive strength increased by 35% compared to basic samples, higher stability of foamed concrete mix and decreased shrinkage deformation.

“…At present, the most used plant in the extraction of fibers are sisal, hemp, flax and bamboo by using different plants parts such as: bast, leaf, seed, fruit, wood, stalk, and grass fibers (Mawaikambo, 2006). Currently, researchers do many studies on the characterization of new lignocellulosic fibers as Okra (De Rosa, 2010;De Rosa, 2011), Posidoniaoceanica (Khiari et al, 2011), Artichoke (Fiore et al, 2011) and Grewia tilifolia (Jayaramudu et al, 2010). In Algeria, there are many plants which can be used in the extraction of fibers (Harche, 1985;Harche et al, 1990;Benahmed et al, 2006) but until now there are any studies on these plants.…”

The aims of this study were to determine the good conditions for fibers extraction from Retama monosperma young stems and their mechanical, physical and chemical characteristics. The fibers were extracted using a range of NaOH concentration from 1 to 16% in a period of treatment of 1 to 24 h, coupled with a physical treatment. For the evaluation of physico-mechanical characteristics, 200 samples were performed in the tensile test. The biochemical composition of the fibers was determined after separation of the parietal compounds. The results show that the best fiber yield was 11.51% obtained by a treatment of 14% NaOH for 8 h, followed by a physical treatment. The fibers biocomposition was 87.3% of cellulose, 7.5% of hemicelluloses and 1% of lignin. The Young's modulus was 13.3 GPa, tensile strength was 110 MPa and a density was 1.3 g/cm 3 . The average fiber length was 155.7 mm. The fibers yield and characteristics showed that R. monosperma plant may in future be suitable source for natural fibers.
