Properties of mortar with waste tyre rubber as partial sand replacement
Around 1000 million waste tyres are generated annually and over 5000 million more are estimated to be discarded by 2030. It is estimated that one waste tyre is discarded per person in developed areas, hence 1 billion waste tyres are disposed worldwide. Waste tyre is difficult to manage as it takes u...

| description | Around 1000 million waste tyres are generated annually and over 5000 million more are estimated to be discarded by 2030. It is estimated that one waste tyre is discarded per person in developed areas, hence 1 billion waste tyres are disposed worldwide. Waste tyre is difficult to manage as it takes up space, is difficult to compress and combustion of tyre releases highly toxic substance into the air. Hence, most of them end up in the landfill, as past research data estimated that currently 4 billion waste tyres can be found in landfills. In this study, up to 30% fine grinded tyre rubber was used as partial sand replacement in type N cement mortar. The rubber was treated with NaOH solution to enhance its ability to bond with the other constituent materials. Tests were conducted to determine the properties of rubberized mortar, including consistency, compressive strength, flexural strength, and water absorption. From the test result, tyre rubber reduced the consistency and strength of mortar. The reduction of strength occurred in a polynomial function with percentage of rubber. However, rubberised mortar has a lower water absorption while still achieving the target strength at up to 20% replacement. |
