“…SF has a very high tensile strength of over 1200 MPa and an elastic modulus of about 200 GPa. The literature confirms its vitality as a superior reinforcement material that ensures satisfying tensile, compressive, flexural and shear strength properties [ 14 , 15 , 16 , 17 ]. By improving the strength per unit quantity of material, SF-reinforced concrete (SFRC) shows lower economic and environmental impact compared to PCC [ 14 ].…”

For the efficient and durable design of concrete, the role of fiber-reinforcements with mineral admixtures needs to be properly investigated considering various factors such as contents of fibers and potential supplementary cementitious material. Interactive effects of fibers and mineral admixtures are also needed to be appropriately studied. In this paper, properties of concrete were investigated with individual and combined incorporation of steel fiber (SF) and micro-silica (MS). SF was used at six different levels i.e., low fiber volume (0.05% and 0.1%), medium fiber volume (0.25% and 0.5%) and high fiber volume (1% and 2%). Each volume fraction of SF was investigated with 0%, 5% and 10% MS as by volume of binder. All concrete mixtures were assessed based on the results of important mechanical and permeability tests. The results revealed that varying fiber dosage showed mixed effects on the compressive (compressive strength and elastic modulus) and permeability (water absorption and chloride ion penetration) properties of concrete. Generally, low to medium volume fractions of fibers were useful in advancing the compressive strength and elastic modulus of concrete, whereas high fiber fractions showed detrimental effects on compressive strength and permeability resistance. The addition of MS with SF is not only beneficial to boost the strength properties, but it also improves the interaction between fibers and binder matrix. MS minimizes the negative effects of high fiber doses on the properties of concrete.

“…The addition of fibres in TGPC improves the modulus of elasticity from 2.13% to a maximum of 32.31%. This may be due to the effect of fibres' high elastic modulus and strong bond between the fibres and the matrix [46,47]. The comparison of modulus of elasticity for all the tested samples are given in Figure 9.…”

The primary aim of this research is to find an alternative for Portland cement using inorganic geopolymers. This study investigated the effect of steel and polypropylene fibres hybridisation on ternary blend geopolymer concrete (TGPC) engineering properties using fly ash, ground granulated blast furnace slag (GGBS) and metakaolin as the source materials. The properties like compressive strength, splitting tensile strength, flexural strength and modulus of elasticity of ternary blend geopolymer concrete. The standard tests were conducted on TGPC with steel fibres, polypropylene fibres and a combination of steel and polypropylene fibres in hybrid form. A total number of 45 specimens were tested and compared to determine each property. The grade of concrete considered was M55. The variables studied were the volume fraction of fibres, viz. steel fibres (0%, 0.5% and 1%) and polypropylene fibres (0%, 0.1%, 0.15%, 0.2% and 0.25%). The experimental results reveal that the addition of fibres in a hybrid form enhances the mechanical properties of TGPC. The increase in the compressive strength was nominal, and a significant improvement was observed in splitting tensile strength, flexural strength, and modulus of elasticity. Also, an attempt to obtain the relation between the different engineering properties was made with different volume fractions of fibre.

In this study, the incorporation of glass fibers in concrete bridge decks has been studied for improving its mechanical properties as well as energy absorption capacity and toughness indices. The mix proportion of 1:3:2 (cement:sand:aggregate) was selected having water-cement ratio of 0.71. For the manufacturing of glass fiber reinforced concrete (GFRC), the glass fibers (2-inch) were incorporated at a percentage level of 1%, 2%, 3% and 4% by weight of cement in concrete mixes. The findings reveal that the split-tensile and flexural strength of GFRC increases at all the percentage levels, however, the compressive strength of the blended mixes get reduced by increasing the dosage of glass fibers in the concrete. Besides, the energy absorption and toughness indices are also studied for different types of loadings (i.e. compressive, splitting-tensile and flexural loadings) up to a percentage level of 4%. The findings reveal that the split-tensile and flexural energy absorption was increased with the increase in the dosage of glass fibers in comparison with the conventional concrete mixes, however, the compressive energy absorption of the blended mixes get reduced by increasing the dosage of glass fibers in the concrete. Whereas, the toughness indices for compressive, spilt-tensile and flexure was increased while increasing the percentage of glass fibers as compared to the conventional concrete. Among the different percentages of glass fibers, its 4% addition gives better results as compared to 1%, 2% and 3%. Hence, the 4% of GF can be suggested to be the optimum percentage of the fibers for the selected mix-design in controlling the resistance of concrete in the bridge decks. Although, the energy absorption of GFRC is lesser in comparison with the toughness indices, GFRC are appropriate for enhancing ductility and resistance against loadings in concrete bridge decks.
