The use of rubber manufacturing waste as concrete additive

Abstract

The rapid development in the field of automobile nowadays, to some extent undermined the environment. This is because the increase in the number of cars increasing cause total waste tires also recorded high volumes. Removal of tires that do not damage the environment can be contained. For example, the waste rubber tires would be breeding places of mosquitoes; while others burned tires will cause air pollution. To overcome this problem is more widespread, many alternatives have been applied one of them related in this study. In this study, rubber tires cut into pieces according to the size of the allowed aggregate in the concrete mix. The size of the tire rubber is cut between 10 - 20mm. Mixture of coarse aggregate replacement rate on rubber tires is 1%, 3 % and 5%. Concrete curing method consists of two methods, which are wet and dry. All samples preserved until 28days. The results compared with the control concrete mix concrete rubber tires. The results show that the rubber mix concrete in this study , the aggregate percentage of the applicable acceptable to have strength concrete control values. Ductility of rubber at the end of the experiment showed that the rubber mix concrete ductility compared with the control concrete more brittle.
