“…In addition to modifying the lumens, alkaline treatment leads to the partial removal of lignin and surface impurities (63), which are hydrophilic components of the fiber (hydroxyl groups -OH) with greater water absorption capacity. Indeed, the crystallinity index (CI) obtained from X-ray diffraction analysis, shown in Figure 8, indicates that the natural fiber had a CI value of 60.75%, consistent with findings in other studies (64,65), while the fiber subjected to alkaline treatment showed a CI value of 66.22%. This increase, corresponding to a 9% rise in crystallinity, aligns with the reduction of impurities and lignin in the fiber, while preserving cellulose (66).…”

The objective of this study is to present a new method of reinforcing masonry using layers of mortar reinforced with short jute fibers. Mortars were produced with 0%, 2% and 3% jute fibers with cementitious matrices free of calcium hydroxide. The effectiveness of the reinforced mortar was evaluated through diagonal compression tests of hollow ceramic brick masonry prisms. The prisms were coated on both sides. The experimental results demonstrated that the diagonal resistance of the fiber system increased by 28 to 30% and presented greater resistance to elastic deformation during load application, with deformation coefficients 2 and 3 times greater for 2% and 3% of fibers, respectively. Therefore, jute fibers prove to be a sustainable and efficient alternative for masonry reinforcement applications, with maximum applied loads considerably higher than the unreinforced system, in addition to better crack control.
