    Abstract

    The environmental issues that occur due to the improper disposal of many waste materials is a growing problem within today’s society due to the increase in population the amount of waste that is being produced is constantly increasing. An increase in population also means an increase in transport needed for the size of populace this means there are more cars on the road across the globe than there was last decade. This increase in cars leads to the increase in waste tyres that are being produced, this tyre waste is what has been looked at in this research along with the use of glass as replacement aggregates for plain concrete and steel fibre reinforced concrete. This research looked at how the workability of the concrete and flexural strength of the concrete was affected by the replacement waste materials, by carrying out experimental tests on six different mixes. It was identified that the use of the waste materials reduce the workability of the concrete in the most part. The waste materials had a negative impact on the flexural strength, with rubber reaching 84% of the control mix strength and when glass was added the strength dropped to only 78% of the control mix strength. However through the experimental procedure it was found that the materials helped with the post-crack properties of the concrete with steel fibres being the best material for post-crack ductility in the concrete.
    Even though this research shows a decrease in flexural strength the use of waste materials is still viable within structural concrete. Further research needs to be carried out on the affect that is caused by the integration of various materials into concrete mixes to allow these mixes to be used more widely in the construction sector.
