The behavior of rubber tyre as fine aggregate in concrete mix

Abstract

Rubber tyres are the most waste material that can be found nowadays. Rubber tyre is the resilient materials that was used by people and make it as the waste tyre disposal after the tyre was not function anymore. Therefore, this material is the one of the largest disposal of waste tyres that had become a major waste management issue in the world at the moment and indirectly can cause air and environment pollution. So that, by replace fine aggregate with rubber tyre it will reduce the pollutions. The purposes of this research are to study the behavior of rubber tyre in concrete mix, to identify physical properties of rubber tyre in concrete mix and to identify engineering properties of modify concrete mix. The test that has been involved in this research is slump test, water absorption test and compression strength test while for curing period that has been conduct in this research is 7 days, 14 days and 28 days. In this research the percentage replacement rubber tyre as fine aggregate that has used is 0 %, 2.5 %, 5.0 % and 7.5 %. Results show increasing rubber tyre in concrete mix, the slump and compression strength will decrease. Moreover, 2.5 % replacement rubber tyre in concrete mix is the best performance in term high compression strength and low ability to water absorb in the concrete.
