“…Post-peak performance was observed with a residual capacity of 14.4 MPa at L/600 and 11 MPa at L/150 in the CC samples. Therefore, the addition of steel fibers enhanced the flexural strength, which is similar to the results in [41,[54][55][56][57][58][59]. Thus, by adding hybrid steel fibers, the flexural and residual capacities increase.…”

In this paper, the mechanical properties and bond strength of composite samples that consist of a conductive concrete (CC) layer and a self-consolidated concrete (SCC) layer are investigated. The bond strength study includes two parameters: (1) surface preparation and (2) casting and testing directions. The surface preparation study shows that, compared to the other methods in this study, the shear key method is the most suitable surface preparation method to fully utilize the CC in a composite. Moreover, the casting direction study reveals that the strength is heavily dependent on the type of test used along with CC’s layer positioning. The flexural strength study confirms that positioning the CC mix in the tensile region is beneficial since it can increase the flexural strength of a structure because of the hybrid steel fibers included in the mixture. Finally, different codes/specifications and published theoretical results are used to predict the CC’s mechanical properties, and the predictions are not as accurate as the SCC predictions, which can be attributed to the presence of conductive fillers in the CC mix.

Concrete has been used for a very long period in construction sites all over the globe. Concrete is very crucial in producing structural members in any building structure. It has to be strong enough to bear the loads of building so that it will not be failed. This article focused on a critical review of concrete containing micro steel fibres (MSF) in order to improve its ductility. In this study, the research is to determine whether the usage of micro steel fibre can improve the compressive and splitting tensile strength of concrete or not. In general, the strength of the concrete improves as the amount of MSF in the matrix increases. All the assessments conducted in all the paper that has been reviewed are following the standard test of British Standard. In a nutshell, the addition of micro steel fibre to concrete does have a huge impact on the tensile and compressive strength. The properties of concrete are expected to enhanced compared to normal concrete; however, the tensile strength does not show any improvement.
