“…As can be expected, addition of bagasse fibers lead to an increase in water sorption leading to increase in thickness due to swelling. 75 On the contrary, increasing level of glass fibers decreased swelling due to the hydrophobicity of the fibers. Flexural modulus of the concrete was increased due to the addition of the bagasse fibers, steel and carbon nanotubes.…”

Fibrous reinforcements, specifically those derived from agricultural sources, instead of steel make concrete more sustainable and provide unique properties to structures. Organic, inorganic and metallic fibers have been extensively studied as reinforcement and as aggregates for concrete. Steel, glass and carbon in fibrous forms have been used as reinforcement along with concrete or as a separate structure to improve performance or buttress dilapidated structures. Although these traditional materials provide good improvement in properties, they are derived from non-renewable and unsustainable sources. Recent focus has been to use renewable and sustainable materials in concrete instead of the traditional materials such as glass, carbon and steel. A plethora of fibers and fibrous materials, especially those derived from agricultural residues, have the potential to be used in concrete and make concrete structure more sustainable and environmentally friendly. In addition to the different types of fibers, various forms of the same fibers have also been used as reinforcement. Fibers, fabrics, tubes, rods and other structures have been used as reinforcement. In this review, we summarize the various types of fibers used in concrete and discuss the potential of using biofibers derived from agricultural residues as reinforcement and aggregates in concrete. We have broadly grouped the fibers into eight categories and further divided into sub-groups depending on the form of the reinforcement. Major focus has been to cover literature on natural fibers and agricultural residue-based reinforcements. Advantages of using fibrous materials including increase in performance properties have been reviewed. Limitations of the reinforcements and approaches to overcome the limitations have also been discussed.

“…The gain in compressive, split tensile, flexural, and bond strengths with sonicated nano-clay mixes ranged between 1.42 and 3.74 times of the gain of those of using nano-clay without sonication. Carbon nanotubes (CNT) are sheets of carbon atoms arranged in a hexagonal shape and rolled to form a cylinder [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Carbon nanotubes have high tensile strength, very low specific gravity, and high surface area.…”

In this paper, a study for the availability of utilizing nano cellulose, as an alternative material for carbon nanotube in nano reinforcing of cement based materials was conducted. One of the main disadvantages of carbon nanotube is its high production cost. Nano-fibrillated cellulose is a natural material extracted from cotton fibers can be used as a nano fiber material for the cement paste. The comparison is done through studying the effect of nano-cellulose on the mechanical properties; through compressive, flexural, and splitting tensile strength and on the microstructure analysis; through a scanning electron microscope, atomic force microscopy, and x-ray diffraction, and comparing with the results obtained through using carbon nanotube instead. NCL and CNT were added to cement paste with the same ratios; 0.02 wt%, 0.04 wt%, 0-06 wt%, and 0.08 wt%. Results show that the optimum percentage for both NCL and CNT was 0.04 wt%. NCL had shown to be a great alternative to CNT as Nano reinforcement to the cement composites not only to enhance the mechanical strengths but also in enhancing the microstructure of the cement matrix.
