Flexural Response of Cement Mortar with Electrical Cable Waste
Electrical distribution cables are disposed of when their length is insufficient and it’s considered as it reaches the end of life, moreover eco-friendly disposal methods are not followed. This study aimed to improve the cement mortar system to meet the nowadays industry requirements with the inclusion of the aforementioned waste fibre extracted from the electrical distribution cables. An aluminium alloy fibre with a diameter of 1.35 mm and 15.0 mm long was used in four-volume ratios as 0.5, 1.0, 1.5 and 2.0% to evaluate the flexural response of the Metal Fibre Reinforced Mortar system (MFRM). MFRM specimens were tested for flexural characteristics in accordance with ASTM C348. The observed stress versus strain curves were critically analysed to compare the ultimate flexural strength, strain at the failure point, flexural modulus, strain energy at the failure and the post-peak behaviour of the system. Compared to the conventional mortar, the ultimate flexural strength of the MFRM was increased by up to 35%. The failures of the systems were observed at higher strain values with the inclusion of fibre, particularly 85% increment was observed with 1.5% of fibre inclusion. Furthermore, the flexural modulus of the MFRM with 1.5% fibres was increased by 174% and the strain energy at the failure was also increased by 105% compared to the reference mortar. The stress versus strain curves imply a curve softening pattern after the crack occurred because of the bridging of the matrices which minimizes the sudden failures of the system. The overall results highlighted that the inclusion of fibres improved the flexural capacity of the mortar and performed effectively at 1.5% fibre volume ratio and the improved mortar system can be used as a cost-effective sustainable building material because of the inclusion of the waste fibres.
