Re-considering sustainable building and design: a cultural change approach. This project will help reduce the 38 per cent of all Australian waste that is produced by the construction industry by addressing the role of the building procurement team in reducing resource usage and eliminating waste. The outcomes of this research will address National Research Priority 1, An Environmentally Sustainable Australia.
Three-dimensional printing of structures using fibre reinforced geopolymer concrete. This project aims to investigate geopolymer binders for cement. Three-dimensional printing using concrete can eliminate expensive formwork but is hampered by a lack of underpinning theoretical material and structural research. Conventional Portland cement’s setting characteristics limit its use for three-dimensional (3D) printing. The project will develop a theoretical framework for the structural properties of ....Three-dimensional printing of structures using fibre reinforced geopolymer concrete. This project aims to investigate geopolymer binders for cement. Three-dimensional printing using concrete can eliminate expensive formwork but is hampered by a lack of underpinning theoretical material and structural research. Conventional Portland cement’s setting characteristics limit its use for three-dimensional (3D) printing. The project will develop a theoretical framework for the structural properties of the 3D printed concrete and flow of geopolymer binder through aggregate bed, and design a fibre reinforcement system. This project is expected to improve construction, reduce injury rates and create high-end technology-based jobs.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
High-Grade CO2 Concrete for Low Life-Cycle Costing and Emissions. This proposal solves Australia’s concrete-waste-storage problems, and lowers the life-cycle costs and greenhouse-gas emissions by creating CO2 Concrete as a world-first material for high-grade applications.

This proposal solves Australia’s concrete-waste-storage problems, and lowers the life-cycle costs and greenhouse-gas emissions by creating CO2 Concrete as a world-first material for high-grade applications. Using an automation system with high-tech software, innovative mixing techniques are proposed to maximise bonding at interfacial transition zones, strengthening CO2 Concrete's quality. The new material CO2 Concrete is created, whose strength and durability are comparable to virgin concrete's, leading to new CO2-Concrete specifications for trials in the construction industry. This diversifies the construction industry, reduces landfill area, greening up Australia on a global scale.Read moreRead less

Summary
Aligned recycled carbon fibre composites for high grade structural elements. By 2025, fibre composites will be a key waste stream worldwide. Current recycling methods are inept as they cause major reduction in mechanical and physical properties of recovered fibre. This project aims to produce high grade, low cost structural component from carbon fibre composite recyclates, and revolutionise their use in construction by carrying out an integrated experimental and advanced computational analyses. ....Aligned recycled carbon fibre composites for high grade structural elements.

Effect of geopolymer cement stabilisation on the fatigue life of pavement sub-bases with recycled demolition aggregates. Road sub-base construction with demolition wastes using geopolymer stabilisation will be researched as Australian stockpiles of demolition wastes, such as concrete and bricks, are growing at 15 million tons per annum. Current sub-base design methods are intended for virgin materials, hence new research is required for waste materials in sub-bases.
