Will geopolymer concretes stand the test of time? In developing new 'green' materials to replace traditional, high-carbon dioxide cements and concretes, it is essential to show that the new materials will be at least as durable as the traditional options. This project will enable prediction of the durability of low-carbon dioxide geopolymer concrete, using laboratory tests, cutting-edge structural analysis and computations.
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.

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

Summary
Enhanced durability of geopolymers through phase engineering. This project aims to research geopolymer phases, their formation thermodynamics and formation kinetics and stability. Alkali-activated (geopolymer) binders and concretes are low-carbon dioxide alternatives to Portland cements and concretes, and ensuring their durability will enable the implementation of this greenhouse-friendly technology in industry.

This project will develop high-performance, lightweight, concrete noise walls and acoustic barriers that use recycled tyre and glass products to improve sound absorption, and address environmental problems associated with the mining of river sands, and stockpiling of waste tyre and glass products. Innovation in noise wall technology consists in developing low-carbon concrete mixes (using less cement) with a maximum amount of recycled product, together with reducing wall thickness, while maintaining the necessary engineering properties such as acoustics, strength, and durability. In addition to higher acoustic insulation, the novel low-carbon, lightweight, panels will improve material handling and affordability of noise barriers.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.
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
Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age crack ....Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age cracking caused by shrinkage. The proposed research will investigate ways of using the new binder system to overcome these weaknesses and to reduce carbon dioxide emission. The expected outcome will be a proven technology for manufacturing new building materials that are environmentally more sustainable and with enhanced properties.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.

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.
