| Popis: | Millions of tires are discarded every year. Disposal or recycling-reusing of waste tire rubber has become a big environmental problem in the world. In this study, it was aimed to determine the freezing-thawing, impact resistance, compressive strength and capillary water absorption rate, when the granulated waste rubber parts are used in the non-load-bearing concrete. Granulated crumb rubbers obtained from waste tires were used at two different grain diameters of 1 and 2 mm as the maximum value. A total of 9 different series were prepared, one of them being the control group and the others being changed with the aggregate in the ratios of 0.5%, 1%, 2% and 4%. In all of the blends, the water/cement ratio was kept constant at 0.50. A drop-weight type impact test was applied to the specimens produced with and without waste rubbers. The impact energy required for the first crack and final dent was determined with the free-falling steel ball at a certain height. Freezing thawing experiments were carried out on the samples with 3% NaCl solution ponded on the surface, and weight losses were determined. As the result, significant improvements were observed in the freezing-thawing and impact resistances of waste tire added samples. Weight loss of specimens because of the freezing-thawing was decreased about 90% and impact resistance was increased different rate depending using rate. © 2018 Elsevier Ltd |
