Description of field of research

According to a Tyre Stewardship Australia (TSA) report, 466000 Tons of End-Of-Life Tyre (EOLT) were generated in Australia between 2018-2019. Annually, this number is around 51 million in Australia. Accumulating EOLT in yards and disposal sites can cause the leaching of toxic chemicals and breeding grounds for mosquitos. Therefore, one of the methods to dispose of the EOLT is to blend it with concrete for various construction applications. Similarly, waste glass also needs new recycling methods. Hence, waste glass also can be used as a replacement for coarse sand and other supplementary cementitious material.

The research aims to develop and optimize mix designs focusing on durability aspects. The preliminary studies found that the inclusion of rubber in concrete increase the permeability and water absorption of concrete and hence is not favourable for the durability of concrete. Also, the inclusion of glass as aggregate replacement cause many adverse effects such as alkali-silica reactions. 

The optimized end product and the findings will be used for real commercial applications by industry partners involved in the project.

Assessment of durability criteria such as rapid chloride penetration, the alkali-silica reaction of aggregates, electrical resistivity, drying shrinkage, autogenous shrinkage, etc. for various concrete mixes containing rubber and waste glass.

Identify a suitable mix design that satisfies the standard design requirements.

Develop laboratory technical skills and knowledge of various construction materials.

Development of soft skills such as writing, literature review, planning, and presentation skills.
