Abstract

The growing problem of waste tyre disposal in the UK can be alleviated if new recycling routes can be found for the anticipated surplus of tyres. One of the largest potential routes is in construction, but usage of waste tyres in civil engineering is currently very low. This study investigates the potential of incorporating recycled rubber tyres into Cement CEM 1 concrete and concrete blocks. It was found that rubberised concrete exhibited very low workability and a marked reduction in strength which inhibits its use for general structural applications. However, the potential was found for producing low strength products such as rubberised concrete block with beneficial properties. The production method replicated that used in industry was produced successfully. As part of the effort in developing new construction materials, it is essential to establish its economic viability as well as its technical viability.
