This project will develop a 'green' sustainable composite steel-concrete building frame system that reduces greenhouse gas emissions throughout the life-cycle of building construction, usage and deconstruction. It will eliminate the use of ordinary Portland cement, which is a major carbon dioxide producer, by using geopolymer concrete made from fly-ash, and will use economic thin-walled, high-strength steel sections. Deconstructability is provided through bolted joints and by using tensioned bolts as shear connectors between the steel skeleton and concrete flooring. This project is underpinned by the extensive background of the candidate, and provides a very timely solution to a major contemporary engineering challenge facing Australia.Read moreRead less

Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in struct ....Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in structural concrete by fully replacing sand and gravel with crushed glass and up to 72% cement with glass powder. This will provide practical solutions to address not only Australia's glass recycling crisis but also the worldwide issue of disposal of waste glass.Read moreRead less

This project will lead a paradigm shift in concrete mix design methodology, which is currently focused on meeting the mechanical performance objectives of concrete, to a holistic approach that maximises durability of concrete alongside its mechanical performance. The approach is based on a hybrid methodology involving mathematical optimisation of concrete mix based on empirically formulated objective functions for durability properties and mechanical properties. The multi-objective nature of proposed optimisation model will allow simultaneous consideration of several design objectives including: minimising the overall risk of cracking, minimising the permeability; and maximising the rate of strength development.

Self-Healing Concrete for Mitigation of Chloride Induced Steel Corrosion. This project aims to develop an intrinsic self-healing concrete using crystalline admixtures for rapid healing of concrete cracking. In marine environments, concrete cracking provides a direct access for chlorides from sea water to the steel reinforcement, leading to early and severe steel corrosion. The self-healing concrete will be designed to address the two main causes of concrete structures deterioration in Australia: ....Self-Healing Concrete for Mitigation of Chloride Induced Steel Corrosion. This project aims to develop an intrinsic self-healing concrete using crystalline admixtures for rapid healing of concrete cracking. In marine environments, concrete cracking provides a direct access for chlorides from sea water to the steel reinforcement, leading to early and severe steel corrosion. The self-healing concrete will be designed to address the two main causes of concrete structures deterioration in Australia: early age cracking due to restrained shrinkage and chloride induced steel reinforcement corrosion. The outcomes of this project will drive the advances in developing and applying crystalline admixture-based self-healing concrete to extend the service life of concrete structures and avoid costly repair.Read moreRead less
