“…Steel fibres, also called steel reinforcing fibres, are a type of reinforcing material used to improve the mechanical properties of concrete and other construction materials or for processes such as soil stabilisation of subgrades. Subgrade soil stabilisation using steel fibre is a construction technique in which steel fibres are incorporated into subgrade soils to improve their strength, durability and loadbearing capacity Steel fibres are typically small, discontinuous strands or particles made from various types of steel, including carbon steel and stainless steel (Hejazi et al, 2012;Marcalíková et al, 2019;Yan et al, 2021). Pedroso et al (2023) conducted a study to evaluate the influence of different curing times on the flexural performance of a soil cement for pavements reinforced with polypropylene fibres and steel fibres.…”

Subgrade soil is an essential component in the design of road structures as it provides lateral support to the roadway. One of the main reasons for pavement failure is subgrade settlement, which leads to a loss of subgrade strength. If the mechanical properties of subsoils are lower than required, a soil stabilisation method may be an option to improve the soil properties of the weak subsoil. Soil stabilisation is one of the techniques for improving poor subsoil, which results in significant improvement in tensile strength, shear strength and bearing capacity of subsoil. Soil stabilisation can be broadly divided into four types: thermal, electrical, mechanical, and chemical. The most common method of improving the physical and mechanical properties of soils is stabilisation with binders such as cement and lime. However, soil stabilisation with conventional methods using cement and lime has become uneconomical in recent years, so an alternative such as fibres may be sought. This review provides a comprehensive comparison of the effectiveness of natural fibres and synthetic fibres in stabilising subgrade soils.

“…The controlled separation of the wire strip until a defined residual web height enables simplified handling of the wires for surface treatment and modification. For example, forming of multidimensional fiber design with hook-like sections is suitable for increasing the cohesion of the composite [9]. Moreover, the fracture surface of the separated wires can be designed for optimum anchoring in concrete [8].…”

The production of wire cores by notch rolling and cyclic bending promises an ecologically and economically efficient manufacturing option for steel fibers. The paper at hand evaluates the influence of wire strips on cyclic bending by applying rolled wire strips of DP600 sheet metal (t0 = 0.8 mm) and a new cyclic bending testing tool. Analysis of material separation with varying parameters, rolling gap d and bending angle β, proves the interdependency of both process step, but indicates reduced adjustability of the notch rolling process. To enable better adjustability of the wire strip’s characteristics and analysis of their effects, wire strip production in the laboratory by notch stamping instead of rolling is aspired. The prior interaction analysis states the web height b, the notch angle α, and the hardening distribution as relevant wire strip’s characteristics to be replicated. Based on experimental analysis, an equivalent of notch rolling by notch stamping is deduced by considering the web height b identical for stamping and rolling, by adjusting the tool’s notch angle αt based on an equation considering geometric evaluations of α, and by taking advantage of the asymmetric hardening distribution of the outer notch which is comparable to rolled wire strip.

“…Among the possible approaches in the case of structural design is the use of lightweight cross-sections, but there is a problem with the location of shear reinforcement. A possible solution to the problem is to use fiber reinforced concrete [1], which exists in a number of variants [2]. They differ in the basic matrix -concrete and the fibers used (shape, material) [3].…”

The paper presents research focused on modeling of lightweight concrete beams combining reinforced and fiber concrete. The paper solves the selected case of the RC beam, which was experimentally tested. The advanced numerical model and calculation used for an experiment into account the non-linear behavior and collapse of the beam. For the experiment, a specific cross-section with an opening that relieves the beam is selected. Non-linear analysis in combination with the finite element method is used for numerical modeling. Specifically, 3D calculation model and fracture-plastic material for concrete are used.
