Abstract
In today's technology, recycling of industrial by product materials has been encouraged as a
result of continual accumulation of different wastes. Waste Gear Inner Wire (WGIW) is
generated and dumped by mechanic's workshops and their consequent environmental
complications due to urbanization; population growth and so on is on the increase. This paper
explored the possibility of using WGIW in Fibre Reinforced Mortar (FRM). Different WGIW
were obtained from various dumping sites within Kaduna metropolis and their geometry,
tensile strength and aspect ratio determined. Based on these physical properties, the WGIW
sample with the highest aspect ratio was selected and used in conducting a trial test using
different % (0.25, 0.75,1, & 2). The outcome of the trial showed that 2% gave the best results
and was used in the entire research. Two concrete samples (fibred & unfibred one) were then
produced and their compressive and tensile strengths determined and compared. Results
indicated that fibreed mortar sample has lower flow value than the control by 13.7%.
However, the fibred mortar has higher compressive and tensile strengths at 56 days by 19%
and 21.1% respectively than the unfibred one. It was concluded that WGIW at 2% volume
fraction could be used as fibre in mortar production. The development of FRM using WGIW
from local wastes was an interesting approach to solving raw material shortage for the current
generation mortar or structural concrete and to reduce waste disposal cost and related
environmental issues in Nigeria among others.
