“…The introduction of 20% CR reverses the trend but still maintains a slump value similar to the benchmark. The conclusions of this family of concrete are similar to that of other researchers [34]. Figure 6d shows the slump test results for the hybrid mixes, containing combinations of SR, CR, and SF.…”

“…Some researchers examined the hybrid concrete mixes: for example, Noaman et al [34] investigated the mechanical properties of rubberized concrete combined with steel fiber. They combined rubberized concrete with different replacement ratios of crumb rubber in plain and steel fiber concrete mixes via the partial replacement of fine aggregate (17.5%, 20%, 22.5%, and 25%).…”

The phenomenon of dumping used tires in Kuwait has reached critical levels, with a landfill containing millions of tires being formed in a remote area, which is a major environmental hazard. Nowadays, recycled rubber is used as a suitable and useful material in civil engineering applications, particularly in the production of “green concrete”. This study aims to see whether recycled tire by-products can be used to make “green concrete” for pavements. Each type of tire by-product was tested individually to examine its properties and effects on a benchmark mix before creating hybrid mixes that contain a combination of the materials. Eleven mixes containing different doses of shredded or crumbed rubber or steel fibers contained within the tires were made to evaluate their impact on the concrete’s slump, compressive strength, split tensile strength, and modulus of rupture. Additionally, twelve hybrid concrete mixes containing different doses of various tire by-products were developed. Preliminary results show that the incorporation of rubber products has a reduction on the concrete’s properties. The use of replacement materials sourced from recycled tires using the dosages investigated in this study does not detract from the usability of green pavement concrete suited for hot weather. The concrete produced in this study could be evaluated for specific properties relating to its road safety in further studies. Additionally, long-term effects of using the concrete can be studied using finite element analysis.

“…compressive and tensile strength), increase the toughness and improve the energy absorption of concrete [1]. Various type of fiber has been researched, such as glass, steel, synthetic and un-synthetic fiber [2]. Adding fibers into concrete create mixtures that are more cohesive and less prone against segregation, thus the interlock and entanglement around aggregate particle tended to reduce the workability.…”

Nowadays the problems of lightweight concrete flexural strength have been approached by adding fiber to the mixture. Meanwhile, waste materials are continuously produced as a result of the modern industry. This paper aims to increase the strength characteristic of both compressive and flexural lightweight concrete by introducing wasted soft-drink cans as fiber reinforced. A comprehensive study has been conducted to investigate the optimal amount of fiber fractions and the effect of fiber shape to the concrete mechanical strength. This study cleared the effect of various fractions (10%, 15% and 20% by volume of concrete), followed by two types of fiber shape (hooked and clipped) to the lightweight concrete compressive and split tensile strength. The experimental results of cylindrical lightweight concrete were compared to the normal lightweight concrete. The result showed that the introduction of 10% of fiber performed in higher tensile strength with an increase of 23%, while the hooked shape of fiber increased the compressive strength by more than 40%. It can be concluded that the introduction of waste recycle tin increased the mechanical properties of normal lightweight concrete, however further study can be performed to effectively increase the strength characteristics.

“…Further, the use of rubber aggregates improves deformation capacity prior to macro-cracking localization, and it is further enhanced by metallic fiber [5]. The mechanical performance of concrete was also evaluated using rubber aggregates only and rubber aggregates along with hooked end steel fibers [11]. Hook ended steel fibers were added with ratio of 0.5% by volume fraction while rubber aggregates was used in different percentages as a replacement of sand.…”

To improve the flexural behavior of thin bonded cement-based overlays, this study was carried out on the use of repair material incorporating amorphous metallic fibers (AMFs) in combination with the rubber aggregates obtained from grinding of worn-out tires. For this study, sixteen mortar mix compositions were prepared to contain AMFs and/or rubber aggregates to be used as overlay material while the substrate used was plain cement mortar. Rubber aggregates were incorporated at three different replacement ratios (i.e., 10%, 20% and 30%) by an equivalent volume of sand, and AMFs were added in three different dosages (i.e., 10 kg/m3, 20 kg/m3 and 30 kg/m3). In this study, composite beams (500 × 100 × 140 mm) comprising substrate (500 × 100 × 100 mm) and repair layer (500 × 100 × 40 mm) were prepared and investigated under flexural loading. Experimental results showed that the increase in rubber content resulted in a decrease compressive strength, flexural strength and modulus of elasticity. Rubberized fiber-reinforced cementitious composites (30R30F) exhibited higher flexural toughness and the flexural toughness improved up to 400%. Toughness and maximum deflection of composite beams enhanced significantly due to synergetic effect of AMF and rubber aggregates. It was observed that before peak load, rubber plays its role by delaying the micro-crack propagation. Results also revealed that the steel fibers reinforcement plays an important role in restraining the crack openings under flexure loading. In the post-peak region, steel fibers control the cracks from propagating further by bridging action and provide higher post-peak residual strength.
