The addition of graphene oxide (GO) and fly ash (FA) to SFRC (steel fiber reinforced concrete) increases frost resistance. Based on the analysis amelioration GO resistance SFRC, improvement mechanism effects FA durability were studied in depth. test blocks’ compressive strength, relative dynamic modulus elasticity, mass-loss rate tested through experiments. pore distribution morphological chara...

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

There have been several difficulties with mesh-reinforced lining constructions because to the complex tunnelling circumstances and varying technical requirements. Thereafter, steel fiber reinforced concrete (SFRC) is promoted as a trustworthy replacement for linings. In this study, we take look at components typical characteristics of SFRC. Cracks or structural failures in linings are summarize...

This paper describes the model for compressive stress-strain behavior of steel fiber-reinforced concrete (SFRC) in Annex L new Eurocode 2 (version 2022-05, EC2), developed within CEN TC250/SC2/WG1/TG2 – Fiber reinforced concrete. The uses functions obtained from correlations with an extensive database comprised 197 well-documented SFRC tests and 484 flexural tests. We detailedly explain derive ...

the main objective of this study is to drive a simple solution for prediction of steel fiber reinforced concrete (sfrc) behavior under four point bending test (fpbt). in this model all the force components at the beam section (before and after cracking) are formulated by applying these assumptions: a bilinear elastic-perfectly plastic stress-strain response for concrete behavior in compression,...

Estimating mechanical properties of concrete before designing reinforced concrete structures is among the design requirements. Steel fibers have a considerable effect on the mechanical properties of reinforced concrete, particularly its tensile strength. So far, numerous studies have been done to estimate the relationship between tensile strength of steel fiber reinforced concrete (SFRC) and ot...

Research reported in this paper was carried to study the water permeability of steel fibre reinforced concrete (SFRC) with varied aspect ratios of steel fibres. Corrugated steel fibres were used in the investigation at constant fibre content of 0.5%. Relationship of water permeability with compressive strength and split tensile strengths has been presented. The water permeability was observed t...

The post cracking behavior of steel fiber reinforced concrete (SFRC) subjected to direct tensile stresses is strongly related the distribution and orientation fibers in crack plane, which can be precisely determined using images obtained by computerized axial tomography (CAT). However, these require processing relate them residual resistances SFRC. objective this paper estimating strength SFRC ...

Shear walls are important vertical and lateral bearing element in structures. While shear with openings fragile due to stress concentration the quasi-brittle behavior of concrete tension. Therefore, additional strengthening rebars required for openings. However, it aggravates problem dense reinforcement which increases steel cage manufacturing compaction still lacks countermeasures against dama...
