Australian research has led to the increasingly widespread commercial use of this technology in a range of areas. Development of a full understanding of the exact chemical structure of geopolymers is essential to finding and developing new applications for these materials as well as maximising their use in known applications.Read moreRead less

Summary
Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner.

There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring together a multi-disciplinary team with complementary strengths to provide an integrated solution for rehabilitation of structures. The core of the network focuses on design tools, linking the various technologies to provide appropriate rehabilitation and understanding of life cycle demands for major infrastructure.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
Improved Management of Australian Port Infrastructure by Development of Predictive Ageing Simulation. Exposure of built infrastructure to corrosive marine conditions causes deterioration and reduced service life. Asset managers lack predictive models of in-service durability. Using data gathered from Australian ports, life-cycle predictions will be developed, simulating durability and incorporating geographical location, structure type, composition, and levels of maintenance. The modelling has ....Improved Management of Australian Port Infrastructure by Development of Predictive Ageing Simulation. Exposure of built infrastructure to corrosive marine conditions causes deterioration and reduced service life. Asset managers lack predictive models of in-service durability. Using data gathered from Australian ports, life-cycle predictions will be developed, simulating durability and incorporating geographical location, structure type, composition, and levels of maintenance. The modelling has not been undertaken on Australian port assets, whereas international models reflect very different infrastructure and exposures and are based on simpler 2D conditions that do not simulate actual deterioration. The three-dimensional (3D) modelling and graphics will be unique worldwide, providing decision support for construction and maintenance.Read moreRead less
Development of Leakage Resistant Well-Cements for Geo-Sequestration of Carbon Dioxide Application using Alkali Activated Slag and Geopolymer Cements. The biggest threat facing life now is climate change due to carbon dioxide (CO2) emissions. Extreme weathers are increasing in frequency and intensity, as evidenced by recent bushfires, and it is predicted to get worse unless carbon mitigation strategies are quickly implemented.

The biggest threat facing life now is climate change due to carbon dioxide (CO2) emissions. Extreme weathers are increasing in frequency and intensity, as evidenced by recent bushfires, and it is predicted to get worse unless carbon mitigation strategies are quickly implemented. Geo-sequestration is the technology of capturing and storing of the CO2 deep below ground for long time (>1000 years). It offers the best hope for large reductions of CO2 emissions. However, CO2-brine stored under pressure is acidic and has the risk of leaking in the long term by dissolving the cement used to seal the pipe wells. This project will develop alternative novel cements which are acid resistant and will not allow CO2 to leak through the sealed wells.Read moreRead less

Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships ....Behaviour of anchors in post-tensioned high-strength concrete slabs. Recently High-strength concrete(HSC) was introduced to minimise the time required for stressing the tendons in post-tensioned construction(PC), which is the preferred construction method for long span slabs in Australia and overseas. Although HSC is an obvious choice for this application, many failures have been observed in the live and dead end anchors of PC slabs and there is in fact very little understanding of relationships between specified concrete properties and performance. Through a systematic experimental and theoretical study, the behaviour of anchor regions of these slabs, including the reasons for failure will be investigated.Read moreRead less

The deleterious effects of extreme fire on structures (e.g. buildings) are significant, whereby structures are designed to ensure that they do not collapse during fire causing human loss. At high temperatures, materials like concrete lose strength and deteriorate. There is a need in Australia for a shared furnace facility between collaborating Institutions to test, share knowledge and expertise, and compare advanced geopolymer materials to different types of concrete when exposed to extreme fire and temperature (e.g. hydrocarbon fire). Geopolymers material offer fire resistance potential, but this needs to be quantified and linked to microstructure prior to commercial acceptance.Read moreRead less
