Potential use of recycled plastic and rubber aggregate in cementitious materials for sustainable construction: A review

A comprehensive overview of geopolymer composites: A bibliometric analysis and literature review

The increasing trend of the use of synthetic products may result in an increased level of pollution affecting both the environment and living organisms. Therefore, from the sustainability point of view, natural, renewable and biodegradable materials are urgently needed to replace environmentally harmful synthetic materials. Jute, one of the natural fibers, plays a vital role in developing composite materials that showed potential in a variety of applications such as household, automotive and medical appliances. This paper first reviews the characterization and performance of jute fibers. Subsequently, the main focus is shifted towards research advancements in enhancing physical, mechanical, thermal and tribological properties of the polymeric materials (i.e., synthetic or biobased and thermoplastic or thermoset plastic) reinforced with jute fibers in a variety of forms such as particle, short fiber or woven fabric. It is understood that the physio-mechanical properties of jute-polymer composites largely vary based on the fiber processing and treatment, fiber shape and/or size, fabrication processes, fiber volume fraction, layering sequence within the matrix, interaction of the fiber with the matrix and the matrix materials used. Furthermore, the emerging research on jute fiber, such as nanomaterials from jute, bioplastic packaging, heavy metal absorption, electronics, energy device or medical applications and development of jute fiber composites with 3D printing, is explored. Finally, the key challenges for jute and its derivative products in gaining commercial successes have been highlighted and potential future directions are discussed.

Current Development and Future Perspective on Natural Jute Fibers and Their Biocomposites

ABSTRACT Synthetic fibers are normally used as reinforcing material to strengthen the concrete. Natural fibers have been considered as the most sustainable alternative for synthetic fibers in both cost and sustainability point of view. In this study, mechanical characteristics of pre-treated bamboo and jute fiber-reinforced concrete (FRC) composites have been evaluated. The performance of treated natural fibers in the enhancement of strength of concrete has been examined. Fibers were added in the percentage proportions of 0.5, 1, 1.5, 2, and 2.5 by the weight of cement in the concrete matrix. The compressive and flexural strength of fiber-reinforced concrete has been experimentally verified. The test results show that maximum compressive strength was obtained as 26.4 MPa and 26.1 MPa for concrete with 1.5% bamboo and 2% jute fibers, respectively, at 28 days of curing. Similarly, maximum flexural strength was obtained as 6.36 MPa and 6.1 MPa for concrete with 1.5% bamboo and 2% jute fibers, respectively, at 28 days of curing. Based on the maximum compressive strength and flexural strength, optimum dosage of treated bamboo and jute fiber has been identified as 1.5% and 2%, respectively. SEM analysis reveals that there is a good bonding between fibers and concrete matrix, and breaking of fibers is due to pulling load and debonding.

Comparative study for efficacy of chemically treated jute fiber and bamboo fiber on the properties of reinforced concrete beams

ABSTRACT This works promotes the idea of simultaneous incorporation of ground granulated blast furnace slag (GGBS) and jute fiber (JF) to develop eco-friendly and ductile concrete. For this purpose, an experimental investigation was conducted, where two concrete families were produced using 0% and 25% GGBS as partial replacements for cement. JF was incorporated as 0%, 0.25%, and 0.5% by volume fractions. Effect of plasticizer was also studied on behavior of jute fiber reinforced concrete (JFRC) with GGBS. Compressive strength-CS, splitting tensile strength-STS, flexural strength-FS, water absorption-WA, chloride ion penetration depth-CIPD, and electrical resistivity-ER were studied. The results showed that with the increasing JF content the CS of concrete declined and STS and FS improved. However, the positive effect of JF on CS was observed in mixes containing GGBS with or without a plasticizer. Incorporation of 0.5% JF without plasticizer improved the STS and FS of concrete by 11% and 17%, respectively. However, after achieving the target workability using plasticizer, the net gains in STS and FS due to the 0.5% addition of JF were 24.3% and 29%, respectively. The negative effects of hydrophilic nature of JF on WA and CIPD resistance of concrete were minimized by using GGBS and controlling workability.
