Effect of waste steel tire wired concrete on the mechanical behavior under impact loading

In this experimental study the effect of waste steel tire wire was investigated on the concrete bollards of mechanical behavior under impact loading. Concrete bollards were produced using three different dimensions with three different volumes of waste steel tire wire (0%, 5% and 10%). The concrete was 30 MPa strength. The concrete bollards were cast into molds with a size of 100x100 mm, 150x150 mm and 200x200 mm and standard length of 1100 mm prism. Nine cube specimens of three different dimensions are tested. 84 kg of an impact load is used with the drop height of 400 mm in this study. Compressive strength tests were achieved. Concrete bollards were kept in laboratory standard conditions. According to the results of study compressive strength of the concrete vary between 25-30 MPa. The use of waste steel tire wire in the concrete bollards contributes to the less crack, less deflection, more acceleration and more energy dissipation at the end of the specimens. The experimental test aimed to research the effect of waste steel tire wired concrete on the mechanical behavior under impact loading as a possible environmentally friendly and sustainable solution. It can be said that the results provide the potential usage of waste steel tire wire manufacturing friendly to nature and sustainability of the concrete bollards. Generally, the usage of waste steel tire wire in concrete could be an innovative method in the construction industry.
