“…The high water absorption of jute ber precludes effective bonding with other materials, thereby limiting its utilisation in geotechnical engineering [13]. The hydrothermal treatment of jute ber can reduce the hydroxyl groups and enhance its surface roughness, thereby improving its adhesive capabilities with other materials [1,11,20]. The objective of this study was to hydrothermally modify natural jute ber in order to enhance its surface roughness and binding capacities with uranium tailings.…”

Microbially induced calcium carbonate precipitation (MICP) is a promising methods for filling and cementing of tailings, offering the advantage of efficient and cost-effective performance. This research employs modified jute fibers combined with MICP to enhance the physical and mechanical properties of uranium tailings as filling materials, and to address the shortcomings of uneven reinforcement and brittle failure of MICP technology. The effect of hydrothermal treatment duration, fiber length, fiber content, and cementing solution concentration on the unconfined compressive strength of MICP-reinforced uranium tailings with different grades was investigated by orthogonal experiments, and the optimal bio-cement parameters were determined. The crystal types of calcium carbonate formed by modified jute fibers combined with MICP were characterized, and the effect mechanisms of modified jute fibers on the mechanical properties of MICP-reinforced uranium tailings were investigated. The results demonstrate that the surface roughness of jute fiber increases after hydrothermal treatment duration, thereby creating increased areas for microbial attachment and reproduction. This results in an increase in the production and uniformity of calcium carbonate in uranium tailings, as well as an improvement in the unconfined compressive strength of the uranium tailings. This is achieved by promoting the growth, reproduction, migration and fixation of microorganisms. The physical and mechanical properties of uranium tailings reinforced with modified jute fiber combined with MICP are optimal when applying uranium tailings with gradation number A3, a cementing solution concentration of 1.5 mol/L, a jute fiber content of 3%, a jute fiber length of 20 mm, and a hydrothermal treatment duration of 2h.

Rheological behaviour is an important factor affecting the flow behaviour of a fluid and many aspects related to this, mainly in the manufacturing process of fiber reinforced composites, either for Newtonian fluids or non-Newtonian fluids. During impregnation process, the viscosity changes with temperatures and their strain rate, has influenced the resin flow behaviour during curing process. In this paper, a review on the rheological studies of fiber reinforced composites for both, synthetic and natural based fibers, respectively, are presented. In addition to that, this review paper highlighting a few research studies conducted in literature on the main factors that affecting the rheological quality and performance of the composites. The aims of this review, mainly to capture the trend ranging from the recent five years back and summarize the various studies via experimental, theoretical or modelling works. Furthermore, also aiming to provide an ideal baseline information in the selection of the methods regarding rheological study to ensure better quality of pre-preg product and fibre reinforced composites can be produced in the author’s future work.
