“…Based on the test data from this paper and previous research [22,23,30,32,33,43,[45][46][47][48], the relationship between the ratio of (f cu − f c0 )/f c0 and λ f and v N is shown in Figure 10, where f cu and f c0 are the cube compressive strength of SFNS-CRC and CRC and λ f is the characteristic coefficient of steel fibers. Although the experimental data look like dispersed, the ratio of (f cu − f c0 )/f c0 has an increasing tendency with the increasing λ f and v N , respectively.…”

The disposal of waste tire rubber has gained more attention from the viewpoint of green, environmental protection, and sustainability. Numerous attempts have been stated on the properties of crumb rubber concrete (CRC) and observed that there is a large reduction of compressive strength and elastic modulus of CRC with the increase of the rubber substitution rate. Based on the CRC with the crumb rubber volume content of 5%, the steel fibers and nanosilica were added to CRC to make steel fiber-and-nanosilica-reinforced crumb rubber concrete (SFNS-CRC) in this paper. The effects of the steel fiber volume content and nanosilica content on the compressive properties of SFNS-CRC were studied, including compressive strength, elastic modulus, peak strain, compression toughness, and failure pattern. The test results indicated that the modulus of elasticity and compressive strength of SFNS-CRC have the increasing tendency with the addition of steel fibers and nanosilica. Moreover, the peak strains have a significant increase with the increase of the steel fiber content and nanosilica replacement ratio. The compressive stress-strain curves of SFNS-CRC gradually plump with the increase of the steel fibers and nanosilica. Finally, the prediction formulas for the compressive strength, elastic modulus, and peak strain of SFNS-CRC were set up. A simple predicted model of the stress-strain curve for SFNS-CRC was proposed, which considers the effect of steel fibers and nanosilica.

“…However, Fu et al [23] found that the effect of concrete containing rubber crumbs on compressive strength depends on the rubber content. e decline in compressive strength due to a high amount of fiber dosage in CRC might be associated with the poor compactness [43].…”

“…e results showed that both fibers increased the energy absorption capacity of cement mortar. Wang et al [19] studied a CRC that was modified by adding steel fibers and nanosilica. e test results showed that the modified CRC with 1.0% steel fiber content had relatively high compressive and splitting tensile strengths.…”

The strength of crumb rubber mortars can be improved by the addition of basalt fibers. However, limited studies have been conducted on basalt fiber crumb rubber mortars (BF-CRM), and the constitutive model is still very immature. In this paper, uniaxial compressive stress-strain curves are obtained for several groups of BF-CRM specimens with different contents. By comparison with the GZH model, modified GZH parameters that can be used in a BF-CRM constitutive model are obtained. Then, taking the support scheme of the main substation of a mine as the background, FLAC3D is used to simulate the roadway support, BF-CRM replaces the ordinary mortars in the original support, and triaxial compression tests are performed at different confining pressures. In this way, the application of BF-CRM in roadway support is studied and analyzed.

“…Additionally, it enhances the absorption energy and expands the region beneath the pressure curve. Several methods have already been introduced into the literature for improving the engineering properties of rubberized concrete, including pretreating the rubber with a NaOH solution (Youssf et al, 2016;Wang et al, 2018), adding materials like silica fume and steel fiber (Onuaguluchi and Panesar, 2014), and pre-coating with limestone powder (Segre et al, 2002). Increased surface roughness of rubber aggregates is the main objective of using NaOH, which also aims to lessen the severe negative effects of the insufficient bonding between rubber particles and cement paste.…”

The difficulties related to non-biodegradable waste management raise the danger of environmental and health issues since millions of worn rubber tires are discarded yearly. Over the past several years, the building industry has been compelled to use this material combined with cement-based products due to the material's accessibility and vast manufacturing volume. Due to its promising properties, including enhanced ductility, damping ratio, and vibration resistance, recycling used tire rubber as a partial replacement of natural stones in concrete is a topic of intense research. Conversely, the rubber aggregator reduces the mechanical characteristics and workability of the resulting concrete mixtures. This study reviews the feasibility of using shredded rubber tire waste as a partial replacement for traditional aggregates in concrete. The properties of the rubberized concrete are discussed with respect to various ratios of rubber tire waste and traditional aggregates. The results of previous studies showed that using rubber tire waste as an aggregate in concrete significantly reduces the mechanical properties of the concrete, including its compressive strength, tensile strength, and flexural strength. On the other hand, using rubber tire waste as an aggregate reduces the weight of the concrete, which may have potential benefits for structural design. Overall, the study suggests that recycling rubber tire waste as an aggregate in concrete is a viable approach for solid waste management and can also provide environmental and economic benefits.
