“…Finally, Soroushian et al [51] used the extrusion procedure to prepare cellulose pulp cement composites with up to 8 wt% fibers. These authors used a laboratory-scale de-airing ceramic extruder which allowed the production of flat specimens with 60 mm width and 8 mm thickness.…”

“…Composites of sisal pulp or sisal staple reached their maximum flexural strengths of 18-20 MPa at fiber contents of about 8%, with an improvement of at least 58% over that of the neat matrix. Finally, Soroushian and co-workers [51] studied the effect of fiber nature (recycled, softwood and hardwood pulps) and content (5, 10 and 15 wt%) on cement composites processed by extrusion. They obtained composites with flexural strengths ranging from 10 to 20 MPa and flexural toughness ranging from 50 to 300 Nm.…”

“…Many studies describing the use of cellulose-based fibers as a reinforcement for cement-based composites have been published [10][11][12][13][14][15][16][17]. Nonetheless, in most of these papers the fibers are used in pulp or staple forms, limiting the improvement of the flexural strength and ductility of the composites, owing to the short length of the fibers, and the maximum quantity that it is possible to mix with the cement matrix (around 4-6 wt.%).…”

This experimental research analyzes the mechanical performance and durability of façade pieces based on Portland cement matrix and flax nonwovens as reinforcement. Two types of pozzolanic additions (silica fume and metakaolin) combined with nonwovens subjected to different treatments to decrease their water absorption are analyzed as potential materials for fiber-cement sheets for building envelopes with high strength and durability. For this purpose, on the one hand, the mechanical performance and chemical composition of various ternary compositions were studied. On the other hand, various treatments were performed on the nonwovens and the nonwoven-matrix adherence was also analyzed. Finally, composites were prepared from some selected treated nonwovens and matrix mixtures, and their mechanical properties and durability were evaluated under four-point bending tests after 28 days of curing in a humidity chamber and after accelerated aging. The composites developed with the treated nonwovens presented very high performance combined with enough durability to be potential candidates for the development of sustainable materials for building envelopes. Highlights-Mechanical performance and durability of OPC/flax nonwovens composites for façade pieces is explored -The effect of two pozzolanic additions combined with nonwoven treatment is evaluated -Significant improvements in the durability using treated nonwovens 3

“…It is stated that the fibres quantity of up to 60-85 % distributes in horizontal plane (in the same direction as moves belt conveyor line) during the formation process [23]. Unfortunately, the difficulties concerning the problem of the allegedly directional structure formation are also met in other manufacture processes of building materials and products which include extrusive [24], fibres pulp processing [25] etc.…”

This paper presents the research on the structure and compressive stress or compressive strength of mineral wool products. The products of chaotic, directional and combinative fibres structure have been studied visually and microscopically. During mechanical tests it was determined that compressive stress (compressive strength) of the stone wool products is dependent on the direction of the load working to the product major face, test specimen dimensions, force increasing rate, fibres distribution (orientation) and methodical peculiarities.
