Abstract
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.
