Buckling of Functionally Graded Multilayer Graphene Nanocomposites. This project aims to contribute to the development of novel lightweight structural members made of graphene nanocomposites with greatly enhanced resistance to abrupt or progressive buckling failure. Abrupt or progressive buckling failure under excessive compressive loads is a common and often catastrophic problem in engineering structures.

This project aims to contribute to the development of novel lightweight structural members made of graphene nanocomposites with greatly enhanced resistance to abrupt or progressive buckling failure. Abrupt or progressive buckling failure under excessive compressive loads is a common and often catastrophic problem in engineering structures. The project intends to develop a functionally graded multilayer graphene nanocomposite structure and to conduct a combined theoretical, numerical and experimental investigation into its buckling and postbuckling behaviours, taking into account the effect of initial imperfection. The project aims to advance the knowledge base of the mechanical behaviour of lightweight nanocomposite structures with improved structural reliability.Read moreRead less
Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix ....Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix concrete industry with a “green” product for the residential construction market. Expected benefits include the increased use of a waste resource (used tyres), reduced use of a scarce natural resource (sand), and the development of an economic but green alternative concrete option for residential builders and owners.Read moreRead less

Three-dimensional concrete printing is a process for construction automation, and adapting recent advances in Additive Manufacturing technologies makes rapid progress possible. However, unsuitable concrete and structural designs and a lack of underpinning material and structural research hamper development. The project will test material properties, fabrication technologies and structural design concepts; and build and test freeform concrete structures. Achieving construction automation is expected to reduce injury rates by eliminating dangerous jobs, create high-end technology-based jobs, and make concrete construction cheaper by eliminating formwork.Read moreRead less
Development of Viable Geopolymer. This project aims to improve the manufacture of geopolymer. Geopolymer (‘green cement’) is produced by alkali activation of fly ash and is a sustainable, low carbon dioxide alternative to conventional cement. Evaluation of raw materials and ensuring reliable performance are critical issues in geopolymer manufacture. The project aims to understand the geopolymerisation process and the behaviour of fly ash and activator in the process. It plans to establish a reac ....Development of Viable Geopolymer. This project aims to improve the manufacture of geopolymer. Geopolymer (‘green cement’) is produced by alkali activation of fly ash and is a sustainable, low carbon dioxide alternative to conventional cement. Evaluation of raw materials and ensuring reliable performance are critical issues in geopolymer manufacture. The project aims to understand the geopolymerisation process and the behaviour of fly ash and activator in the process. It plans to establish a reactivity index to quantitatively evaluate fly ash and match it with activator to achieve efficient activation with predictable properties. The project is expected to result in a scientific tool to assess fly ash suitability and a method to design and produce viable geopolymers.Read moreRead less
Development of controllable and durable green concretes through the understanding of feedstock chemistry and geopolymerisation mechanism. This project will develop key knowledge and technologies towards in geopolymer applications, evolving the current polluted cement/concrete industry into a much greener industry with up to 80 per cent lower carbon emissions. Successful completion of this project will keep Australia at the leading frontier of green technology and green industry.

Engineering the strength and consolidation of reclaimed soft soil. This project aims to strengthen reclaimed soft soils by controlled desiccation. Soft soil is a significant engineering challenge for many industry sectors in Australia and worldwide. The disposal of dredged soft soil is costly and time-consuming, and failure of soft mine tailings is an environmental catastrophe that can cause loss of life and interrupt mining production. This project will research the underlying processes of material behaviour, by developing new electromagnetic measurement and modelling methods to predict material strengths at the micro and macro scales during desiccation. The new approach is expected to lead to innovative solutions to bearing capacity and settlement problems associated with soft soils.Read moreRead less
