Flexural Properties and Microstructure Mechanisms of Renewable Coir-Fiber-Reinforced Magnesium Phosphate Cement-Based Composite Considering Curing Ages
Polymers, 2020Co-Authors: Liwen Zhang, Zuqian Jiang, Wenhua Zhang, Sixue Peng, Pengfei ChenAbstract:As a renewable Natural Plant Fiber, Coir Fiber (CF) can be used to as an alternative to improve poor toughness and crack resistance of magnesium phosphate cement (MPC), replacing such artificial Fibers as steel Fiber and glass Fiber and thereby reducing huge energy consumptions and large costs in artificial Fibers’ production and waste treatment. Aiming at examining the effects of CF volume concentrations on MPC flexural properties, this study employed a typical three-point bending test, including thirty cuboid specimens, to investigate the flexural strength, load-deflection behavior, and flexural toughness of MPC with different CF volume concentrations from 0% to 4% at the curing age of seven days and 28 days. Results demonstrated that CF presented similar effects on MPC’s properties at two curing ages. At both curing ages, as CF grew, flexural strength increased first and then decreased; specimen stiffness, i.e., MPC elastic modulus, displayed a decreasing trend; and flexural toughness was improved continuously. Additionally, modern microtesting techniques, such as, scanning electron microscopy (SEM) and energy dispersive X-ray detection (EDX), were adopted to analyze the microstructure and compositions of CF and specimens for explaining the properties microscopically.

Flexural Properties of Renewable Coir Fiber Reinforced Magnesium Phosphate Cement, Considering Fiber Length.
Materials (Basel Switzerland), 2020Co-Authors: Liwen Zhang, Zuqian Jiang, Wu Hui, Wenhua Zhang, Yushan Lai, Weile Zheng, Li JingAbstract:Coir Fiber (CF), a renewable Natural Plant Fiber, is more competitive in improving poor toughness and crack resistance of magnesium phosphate cement (MPC) than artificial Fibers, due to its slight energy consumptions and low costs in production and waste treatment. In this paper, a typical three-point bending test was carried out to study the effects of CF length on MPC flexural properties. A total of forty-two cuboid specimens were employed to investigate the flexural strength, load-deflection behavior, and flexural toughness of MPC, with CF lengths varying from 0 to 30 mm at the curing age of 7 days and 28 days. Results showed that, at both two curing ages, MPC flexural strength first increased with CF length increasing, and then deceased when CF length exceeded the threshold. However, with the increase of CF length, MPC flexural toughness increased continuously, while MPC elastic modulus displayed a decreasing trend. Additionally, Modern micro testing techniques, such as scanning electron microscope (SEM) and X-ray diffraction (XRD), were also used to study the microstructure and phase compositions of specimens for further explaining the themicroscopic mechanism.

a state of the art review on soil reinforcement technology using Natural Plant Fiber materials past findings present trends and future directions
Materials, 2018Co-Authors: Sivakumar Gowthaman, Kazunori Nakashima, Satoru KawasakiAbstract:Incorporating sustainable materials into geotechnical applications increases day by day due to the consideration of impacts on healthy geo-environment and future generations. The environmental issues associated with conventional synthetic materials such as cement, plastic-composites, steel and ashes necessitate alternative approaches in geotechnical engineering. Recently, Natural Fiber materials in place of synthetic material have gained momentum as an emulating soil-reinforcement technique in sustainable geotechnics. However, the Natural Fibers are innately different from such synthetic material whereas behavior of Fiber-reinforced soil is influenced not only by physical-mechanical properties but also by biochemical properties. In the present review, the applicability of Natural Plant Fibers as oriented distributed Fiber-reinforced soil (ODFS) and randomly distributed Fiber-reinforced soil (RDFS) are extensively discussed and emphasized the inspiration of RDFS based on the emerging trend. Review also attempts to explore the importance of biochemical composition of Natural-Fibers on the performance in subsoil reinforced conditions. The treatment methods which enhances the behavior and lifetime of Fibers, are also presented. While outlining the current potential of Fiber reinforcement technology, some key research gaps have been highlighted at their importance. Finally, the review briefly documents the future direction of the Fiber reinforcement technology by associating bio-mediated technological line.
