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

This project aims to formulate a new mix design for sustainable and resilient infrastructure materials with radically improved material properties and performance, as well as reduced life cycle cost and impact on the environment and societies. The aim of the project is to investigate the effect of dune sand and graphene oxide on mechanical properties and durability of concrete composites including properties and strength relation and alkali-silica reaction in concrete. The optimal mix design will be supported by the understanding of the interaction between graphene oxide, water molecules, dune sand and cement at nanolevel via scanning electron microscopy (SEM) and molecular dynamics simulations.Read moreRead less

The project expects to generate new fundamental knowledge in the area of building cooling materials, via multidisciplinary utilisation of cutting-edge construction materials and design. The expected outcome of the project will place Australia in a competitive position in advanced green building infrastructure and highly demanded energy-saving technologies. This should provide benefits, such as significantly decreasing building energy consumption, and, thus reducing greenhouse gas emission.Read moreRead less

Active rheology control of fresh concrete using responsive additives. This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages. ARC will also be useful to solve the major barrier faced by 3D concrete printing (3DCP) from becoming a ....Active rheology control of fresh concrete using responsive additives. This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages. ARC will also be useful to solve the major barrier faced by 3D concrete printing (3DCP) from becoming a practical way of construction. 3DCP is an emerging idea for construction but a major barrier is that concrete needs to flow during pumping and extrusion but become stiff soon after placement. This project will explore ARC for achieving the “flow-on-demand” desired by both concrete pumping and 3DCP applications.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 aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosion prediction models using classical and recently available 100 year data from Europe, the Pacific, Australia and also new project-specific experimental data. These models are expected to be of benefit for Australian engineering consultants in maintain their internationally competitive edge in offshore engineering.Read moreRead less

The project aims to develop a new rheological model for 3D printable concrete for construction. 3D concrete printing is an innovative and promising construction technique, but the main impediment to progress is lack of suitable material technology. In this study, a new stress and time dependent flow model will be formulated and implemented as a computational model. The model will facilitate the study of the effect of different concrete formulations, pumping and printer parameters on the primary printing properties, namely, pumpability, extrudability and buildability. The new model will also enable active control and modification of rheological parameters on-the-fly during large-scale printing, which is not currently possible.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.
