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 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. Geo-polymer is a sustainable material and has adjustable setting characteristics and better fibre-matrix interface properties than conventional cemen ....Three-dimensional printable geo-polymer with orientable fibres for construction application.

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.

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
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.
