The Use of Recycled Rubber Tyres in Concrete Construction
[attachment=16606]

Introduction
Background
The disposal of waste tyres is becoming a major waste management problem in the
UK. It is estimated that 37 million car and truck tyres are being discarded annually and
this number is set to increase, in line with the growth in road traffic and car ownership,
by a further 39% by 2011 and 63% by 2021 (Martin, 2001).


Objectives
The overall objective of the project is to investigate the feasibility of incorporating
rubber tyre chips as a replacement for natural mineral aggregates in concrete.
The specific objectives of the project are as follows:
1. To establish the density and grading of the rubber crumb and chip aggregate,
2. To establish a family of concrete mixes which produce concrete with prescribed
properties,
3. To evaluate the structural properties of concrete made using rubber aggregate,
4. To undertake a cost-benefit analysis and investigate the market potential of
rubberised concrete products.

Characteristics of fresh rubberised concrete
In order to assess the characteristics of fresh rubberised concrete, the following aspects

were considered:
