Abstract
Aluminium electrical wires scrap that are available after the demolition of buildings is generally left unused in the market. It is a lightweight material capable of exhibiting strength properties with a potential for reusability in concrete. The aluminium fibres used in this work were looped at its ends to enhance its bond strength with the concrete. This paper shows the outcomes obtained from an experimental study on the mechanical properties of aluminium fibre reinforced concrete to attain its ideal fibre volume fraction. A total of three grades of concrete and five different fibre volume fractions at (0, 0.5, 1, 1.5 and 2%) were incorporated in this study. After 28 days of curing, the compressive strength and split tensile strength of the concrete specimens were determined through laboratory tests. Also, based on the experimental outcomes a regression analysis was performed to predict strength of fibre-reinforced concrete using statistical modelling based on the experimental outcomes. This indicate the effectiveness of interaction of looped end aluminium fibres with the concrete matrix.
