A large number of reinforced concrete (RC) structures over time have their usage altered, and they experience deterioration or damage caused by different causes. There are more than billions of tires used for replacement every year in global, and more than half of them are abandoned and are waiting to be disposed. The black pollution which is hard to be biodegrade does not only pose potential risks to the environment, but a threat to the health of human beings who work in the scrap zone. These are the two main issues that focused on this study. Different steel fibres like industrial steel fibre, recycled steel fibre and hybrid steel fibre are used for t he construction of columns. Steel fibre obtained by the recycling of tyres are known as recycled steel fibres which reduces the dumping of tyres. The premade tested squared cross section fibre reinforced concrete columns was placed inside a steel tube and the space between the column and steel tube was filled with high strength concrete. The test results showed that the column with industrial steel fibres is having high strength compared to others. The influence of the test parameter on the compressive strength was investigated. In addition, specimen failure modes and load vs deformation relations were registered.
