Abstract
What to do with scrap tyres that are currently dumped to landfill is a significant problem in Australia and the rest of the world. Scrap tyres are among the largest and most problematic sources of waste, due to their durability and the large volume of discarded tires every year. Scrap tyres can be placed in a dump, or piled in a large hole in the ground. However, these dumps serve as a breeding ground for mosquitoes. Moreover, tyres may catch fire and that is notoriously difficult and costly to extinguish. Across the world, one billion tyres reach the end of their useful lives every year and 0.5 billion more are expected to be discarded each year by 2030. This rapid increase provides added motivation to find different ways for re-using this waste rubber. One possibility being explored is to use crumbed rubber from waste tyres to replace part of the natural aggregates in conventional concrete resulting in a new product called crumb rubber concrete (CRC). Using scrap tyres in concrete conserves valuable natural resources and reduces the amount of waste entering landfill. CRC is an attractive alternative to conventional concrete because of its relatively high ductility, toughness, and damping ratio, but it has lower compressive strength.
In this research, the behaviour of CRC was investigated at both the concrete material level and the structure application level. For the concrete material level, the mechanical properties of 12 CRC mixes were investigated in order to provide additional information necessary to support the further development of the proposed bridge columns. The behaviour of 18 concrete cylinders consisting of CRC or conventional concrete encased in FRP tubes having different thicknesses was also investigated.
