“…The flow values reduced by ~18% using 1wt.% MCC in the absence of sisal fibres and by ~24% with 0.25% sisal fibres. The reason for the decreased flow values of fresh mortars due to the presence of sisal fibres and MCC was their hydrophilic character which led to absorption of water from the mortar pastes reducing their flow properties (Cao et al, 2015;Hospodarova et al, 2018). MCC had slightly higher effect on the flow properties due to their higher surface area and ability to absorb water more quickly.…”

This research work attempts, for the first time, to use sisal fibres and microcrystalline cellulose (MCC) in combination for developing multi-scale cementitious composites with improved strength, modulus as well as fracture energy. MCC (0.1% to 3.0 wt.%) was first dispersed in water with the help of Pluronic F-127 surfactant (20% of MCC wt.) using ultrasonication and subsequently, the MCC suspensions were added to cement-sand mixtures containing sisal fibers (0.25 to 2 wt.% of cement). Visual observation, UV-Vis analysis and optical microscopy suggested that ultrasonication for only 15 min led to homogeneous MCC suspensions without significant sedimentation and Pluronic significantly reduced the total agglomerated area and the average MCC particle size in the suspensions. The use of up to 2 wt.% sisal fibres (without MCC) increased the fracture energy of cementitious composites by 351% (after 28 days hydration) but reduced the compressive and flexural strengths by 38% and 13%, respectively. On the contrary, MCC (without sisal fibres) could strongly improve the compressive strength (20.5% using 0.1wt.% MCC) but was not found so effective in improving the fracture energy (improved by 29% using 0.1 wt.% MCC). However, multi-scale reinforcements containing 0.1 wt.% MCC and 0.25-0.5 wt.% sisal fibres led to improvements of up to 18.4%, 30.1%, 30% and 100% in the compressive strength, flexural strength, flexural modulus and fracture energy of composites, presenting distinct advantages over only sisal fibre or MCC-based reinforcements. The results indicated the formation of higher amount of hydration products in multi-scale composites due to the positive effect of MCC on cement hydration. Superior hydration in the multi-scale composites resulted in a denser microstructure with a lower pore size and an improved fibre-matrix interface, improving significantly the strength, modulus and fracture energy.

“…These data were also in compliance with other studies with similar textile synthetic and recycled fibers, which showed that 0.5% of fibrous reinforcement is efficient for increasing mechanical properties. 39,64 On the other hand, addition above 1 wt% decreased the mechanical properties of cementitious composites reinforced with cellulose fibers as mentioned by Ghasaei et al 65…”

This study presents an analysis of the possible use of a viscose rayon (CV) fiber from textile industry wastes to develop a reinforced cementitious composite as an alternative for textile discharge valorization. Several techniques were used to characterize precursor fibrous waste material such as SEM, FT-IR, DSC, and TGA. The experimental studies were conducted based on a conventional cementitious mortar (control) and four different fiber contents (0.5, 1, 2, and 4 wt%). For mechanical behavior analysis, uniaxial compressive strength tests were carried out at different ages (7, 14, and 28 days after production). The results showed favorable CV fiber addition as reinforcement up to a maximum limit. The optimum concentration of fiber was 0.5 wt% (FRC0.5), which provided 28 days of higher compression strength. The addition of CV waste as reinforcement in cementitious matrix resulted in an improved compressive strength above 20.6% compared to the conventional non-reinforced mortar. Furthermore, CV fiber addition improved the ductile behavior of the new composite allowing a controlled failure, even after maximum rupture loading.

“…Recent studies have used cellulose fibres for the development of films addressing mechanical [ 21 , 22 ] and optical properties [ 23 , 24 ]. However, a few studies have reported excellent vapor barrier properties in packaging applications [ 25 , 26 , 27 ] and their use in the construction industry [ 28 ].…”

This study focuses on the development of advanced water-resistant bio-based membranes with enhanced vapour permeability for use within building envelopes. Building walls are vulnerable to moisture damage and mold growth due to water penetration, built-in moisture, and interstitial condensation. In this work, breathable composite membranes were prepared using micro-fibrillated cellulose fiber (CF) and polylactic acid (PLA). The chemical composition and physical structure of CF is responsible for its hydrophilic nature, which affects its compatibility with polymers and consequently its performance in the presence of excessive moisture conditions. To enhance the dispersibility of CF in the PLA polymer, the fibers were treated with an organic phosphoric acid ester-based surfactant. The hygroscopic properties of the PLA-CF composites were improved after surfactant treatment and the membranes were resistant to water yet permeable to vapor. Morphological examination of the surface showed better interfacial adhesion and enhanced dispersion of CF in the PLA matrix. Thermal analysis revealed that the surfactant treatment of CF enhanced the glass transition temperature and thermal stability of the composite samples. These bio-based membranes have immense potential as durable, eco-friendly, weather resistant barriers for the building industry as they can adapt to varying humidity conditions, thus allowing entrapped water vapor to pass through and escape the building, eventually prolonging the building life.
