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.

Nowadays, the improvement of construction materials towards sustainable construction materials had become important. Due to the hot and sunny climate in Malaysia, the consumption on electricity increases. This causes a decrease of comfort in residence. The objectives of this research was to evaluate the thermal properties of concrete containing micro steel fibres (MSF). In this study, a series of concrete cubes that consists of different percentage of MSF (0%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%) was made in order to carry out compression test. Then, a Hot Guarded Box was used to obtain the optimum percentage of MSF in the concrete for thermal conductivity. As a result, the optimum percentage of MSF obtained from the compression test was 0.8% with a reading of 25.7Mpa. While, the optimum percentage of MSF obtained for thermal conductivity 0% with a reading of 0.34 W/mk. As a conclusion, it was proven that the inclusion of MSF in a concrete matrix will increase the thermal conductivity.

Concrete is widely used in the engineering field, particularly in construction. Despite its widespread use in the construction industry, concrete is brittle and has a number of drawbacks, including low tension and crack resistance. As a result, many researchers discovered a way to enhance concrete ductility through adding micro steel fibers (MSF) as a reinforcement. This study explores the impact of MSF on slump height, and the toughness of various concrete. To obtain relevant paper for this research, a systematic literature review was used. When 0.5% to 2% MSF were present in the concrete composite, the result shows a positive increment on its strengths. Meanwhile, the toughness impact of self-compacting concrete (SCC) is reduced depending on what type of water used during the mixing process. Aside from that, adding 0.5% to 2% MSF increases the tensile strength of SCC and ultra-high performance concrete (UHPC). Ultimately, incorporating MSF with concrete to increase the durability is a great idea.
