“…In recent years of literature review about SIFCON and the beams with FRP/GFRP, different studies have been carried out on the mechanical, physical, durability properties of SIFCON and flexural/shear behavior of beams with FRP/GFRP. Jerry and Fawzi [25] investigated the impact resistance and density properties of SIFCON. The steel fiber and polyolefin fibers were added to the SIFCON mixture.…”

The SIFCON concrete reinforced with glass-fiber reinforced polymer (GFRP) bars can provide a construction system with high durability and strength. Slurry infiltrated fibrous concrete (SIFCON) is a new type of conventional fiber reinforced concrete. The aim of this paper is to evaluate the flexural and shear behavior of the SIFCON concrete beams reinforced with GFRP bars were evaluated under four-point bending and three-point shear tests. The parameters investigated were material type of longitudinal reinforcement (steel and GFRP), transverse reinforcement type (steel and mesh) and mesh reinforcement spacing (25 mm and 12 mm). For this purpose, a total of twelve SIFCON concrete beams with steel and GFRP bar as longitudinal reinforcement measuring 150x150x800 mm were cast. Moreover, stirrup and mesh reinforcement as transverse reinforcement are another main parameter of this study. The test results showed that the effects of longitudinal and transverse reinforcement type and mesh spacing on the strength, crack propagation, and energy dissipation capacity of RC beams under bending and shear were experimentally investigated. The use of steel longitudinal reinforcement in both four-point and three-point tests increased the bending moment and shear strength compared to beams with GFRP. Moreover, although the use of mesh reinforcement in reinforced concrete beams under four-point bending reduced the strength, it increased the strength in beams with GFRP. In the samples under the shear force, the use of mesh reinforcement in the steel reinforced group increases the shear strength, but the use of mesh reinforcement in the GFRP group decreases the shear strength.

This article investigates the degradation of stiffness in high and standard-strength concrete due to the influence of repeated loading and considers the non-linear behavior arising from localized or natural defects of concrete. The article also refers to the models from existing literature that evaluate the characteristics of concrete by enhancing its physicochemical properties through the application of natural and synthetic fibers. The impact of the service load, which influences the change in concrete stiffness, is illustrated using the elastic–plastic concrete model. The elastic–plastic model of concrete, combined with experimentally determined data such as elastic and residual deformations, simplifies the analysis of concrete beams or surface elements. This model enables static solutions of inelastic materials based on the classical theory of elasticity. The degradation of element stiffness in this model is described by the local increment of the rotation angle. Based on the model we can assume a constant stiffness along the length of the beam before as well as after exceeding the value of the cracking moment. In the case of cyclic loads, it can be assumed that residual deformations have the greatest influence on the displacement values, which in the calculation model are described by the component of the angle of rotation in the crack, describing permanent displacements.

Development of an Engineered Slurry-Infiltrated Fibrous Concrete: Experimental and Modelling Approaches

Concrete is the central pile for the infrastructure that maintains civilisation and human life. The concrete industry faces many challenges, including improving mechanical properties, eco-friendliness, and durability. In this context, the present study focuses on evaluating and modelling themechanical properties of engineered concrete, namely slurry-infiltrated fibrous concrete (SIFCON). The main experiments will be devoted to measuring and modelling the failures of slabs made from SIFCON under two loading systems, namely static and impact loading systems. The model was developed using a non-linear finite element analysis. The experiments considered the influence of the geometry of the reinforcement steel fibres (hook-end fibres, microfibres, and combined hook-end and microfibres), sizes of fibres, and slab dimensions. The outcomes of this investigation showed that increasing the slab’s thickness enhances the load-bearing capacity of the SIFCON slab, and the microfibres and combined hook-end and microfibres improved the load-bearing capacity of the slab compared to the hook-end fibre. Generally, it was noticed that the outcomes of the experiments agreed with the modelling outcomes. Nevertheless, it was noticed that experimentally measured axial deformation was more significant than the predicted axial deformation. In summary, the difference between experimental and modelling outcomes was 1.1–10.2%, with a standard deviation of 0.0264. Based on the excellent ability of SIFCON to resist impacts and dynamic loads, it is recommended to be used in pavements, military structures, nuclear reactor walls, and in areas subjected to high bending moments, such as corner connections subjected to opening bending moments.
