“…In this theoretical calculation, the values encompassed in Method 1 are obtained by using the elasticity modules calculated with the help of the formulation defined for LWC. In Method 2, calculations are made with the help of known formulas (Eqs [1][2][3][4][5][6]) for standard concretes.…”

“…They stated that waste tire rubber aggregate, in which both fine and coarse aggregates are replaced by 6% rubber aggregates, significantly improves the impact resistance and ductility properties of concrete. Alwesabi et al [6] investigated the effect of hybridization of polypropylene fiber and steel fiber on the fracture properties of plain and rubberized concrete (derived from waste tire) to determine the optimized blend ratio of fibers. They reported that concrete compressive and tensile strengths decrease due to crumb rubber change, but increase with hybrid (0.1% polypropylene, 0.9% steel) fiber mixture.…”

“…Recently, there has been great interest in the impact behavior and engineering properties of fiber-reinforced concretes. This is because fiberreinforced concrete behaves more ductile than conventional concrete [4,6]. Various fibers such as metallic, glass, and synthetic polymer fibers are used as reinforcement elements in concrete structures.…”

The paper is an analysis of the experimental and theoretical behavior of cementitious plate containing waste ethylene vinyl acetate (EVA) with and without reinforcement with glass fiber woven fabric (GFRP) under low-velocity impact load effect. Cementitious plates of 150 mm × 150 mm size and three different thicknesses (15 mm, 30 mm, 50 mm) are produced by replacing the cement mixture aggregate with EVA at 0%, 18%, 32%, 45%, and 56% by volume of aggregate. Then, the cementitious plates are coated with GFRP using vacuum infusion method. The effect of EVA and GRFP coatings on the dynamic impact behavior of cementitious plates is investigated by applying a low-velocity impact test on the produced cementitious plates with an impactor of 18 mm diameter, 10.50 kg weight, and 500 mm height. The data obtained from the experimental results are analyzed based on the mass-plate theory, lightweight (LWC) and normal weight (NWC) concrete, and the consistency of the theoretical results with the experimental results is compared. It has been determined that the use of NWC is more suitable for cementitious plates with an EVA replacement rate in the range of 0–32%, while the use of LWC offers more optimum results if the EVA ratio is in the range of 32–56%. Especially when the EVA displacement exceeds 32%, it causes excessive void formation in the structure, resulting in a reduction in the dynamic impact loads of cementitious plates. GFRP coating with vacuum infusion method is not recommended for cementitious plate structures when the EVA replacement rate exceeds 32% by volume of aggregate.

“…Cajka et al [24] proved the positive influence of fiber concrete slabs on the increased load capacity and more favorable deformations compared to conventional concrete slabs. Further, some researchers have proposed that hybrid fiber-reinforced material offers better mechanical characteristics individual fibers [25][26][27]. Zhang et al [26] conducted mix experiments that included steel fiber, polyvinyl alcohol fiber, and basalt fiber.…”

In this work, to reduce the probability of brittle failure in the support structure of deeply buried high-stress soft rock roadways, hybrid-fiber reinforced rubber concrete (HFRRC) was investigated using the orthogonal test, and the effects of various factors on the performance were studied. The mechanical properties, pore structure, and microstructure of rubber concrete reinforced by basalt fiber (BF) and polyvinyl alcohol fiber (PF) were studied from macroscale, mesoscale, and microscale perspectives. The results revealed that the content of the rubber particles has a significant impact on strength. Further, the addition of the hybrid fibers to the concrete was found to have a positive effect on the splitting tensile strength and the flexural strength. However, no significant effect was observed on the compressive strength. Furthermore, it was found that the content of BF and PF have a significant impact on the energy dissipation capacity and ductility, and the influence of the PF content is greater than that of the BF content. The concrete with 10% rubber particles of 1–3 mm, a volume fraction 0.3% basalt fiber, and a volume fraction 0.2% polyvinyl alcohol fiber was obtained as the optimal mix proportions. Moreover, it was found that the random distribution of the rubber particles and the hybrid fibers optimized the pore structure, inhibited the expansion of the cracks, and reduced the brittleness of the concrete. The findings of this study can provide a useful reference for the application of an environmentally friendly material with recycled rubber aggregate and hybrid fiber.
