Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation ....Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation of results. While theoretical developments of this project are general, in the sense that they are not restricted to particular engineering disciplines, the four chosen applications closely align with two major research priorities namely An Environmental Sustainable Australia and Promoting and Maintaining Good Health.Read moreRead less

Summary
Three-dimensional concrete printing facility. This project aims to develop concrete types of construction materials and structural forms. 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.

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. 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, ....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. 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
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
Additive manufacturing of functionally graded geopolymers. This project aims to use contour crafting for three-dimensional printing of functionally graded geopolymer concrete. Contour crafting has been touted for producing uniform structural members made of conventional concrete mixtures. This project will develop the existing technique to produce microstructurally graded geopolymer structures and include functionally graded placement of fibre within a geopolymer matrix.

This project aims to use contour crafting for three-dimensional printing of functionally graded geopolymer concrete. Contour crafting has been touted for producing uniform structural members made of conventional concrete mixtures. This project will develop the existing technique to produce microstructurally graded geopolymer structures and include functionally graded placement of fibre within a geopolymer matrix. It will investigate mechanical, thermal and durability properties of printed composite structures. The outcome of this research could lead to cost-effective automated production of specialised structural components.Read moreRead less

Three-dimensional printable geo-polymer with orientable fibres for construction application. This project aims to develop a fibre-reinforced geo-polymer for three-dimensional concrete printing (3DCP). 3DCP allows freeform construction without the use of expensive formwork, but is limited by the range of printable concretes and reinforcing methods.
