Thin-walled Structures Subjected to Impact and Blast Loading. Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads.

Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads. The investigators will establish the most economical means of designing passive blast protection into thin-walled structures and hence, Australia's critical infrastructure. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the ....Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the industry demand. This project investigates the use of fly ash to make geopolymer concrete, without using any Portland cement, to find usage for part of the 11 million tons/year of fly ash produced as a waste from coal power stations in Australia.Read moreRead less
Development of an Alkali Activated Slag based Construction Material for High Fire Risk Infrastructures. This project will develop an alkali-activated slag (AAS) based construction material for tunnel construction. In tunnels, conventional concretes are likely to 'spall' in a hydrocarbon fire accident, possibly resulting in a tunnel collapse. The project is set to develop a spalling-resistant AAS as an alternative to conventional Portland cement, which is responsible for 6.5 million tons of gre ....Development of an Alkali Activated Slag based Construction Material for High Fire Risk Infrastructures. This project will develop an alkali-activated slag (AAS) based construction material for tunnel construction. In tunnels, conventional concretes are likely to 'spall' in a hydrocarbon fire accident, possibly resulting in a tunnel collapse. The project is set to develop a spalling-resistant AAS as an alternative to conventional Portland cement, which is responsible for 6.5 million tons of greenhouse gas emissions in Australia per year, whereas AAS is based on slag, an industrial waste product. The project also seeks to provide better understanding of the spalling phenomenon so that the engineers can design fireproofing for conventional concrete tunnels with confidence.Read moreRead less
High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators wi ....High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount.

However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads.

Summary
Collection, Sharing, Visualisation and Analysis of locally gathered information from geographically remote areas vulnerable to tidal waves. This project will set up a virtual organization for tsunami related data analysis using grid technology. Due to geologically remote areas/countries involved the sharing of seismic, tidal and other locally gathered tsunami related information is critical to issuing a warning. In collaboration with Australian and International partners, this project will explo ....Collection, Sharing, Visualisation and Analysis of locally gathered information from geographically remote areas vulnerable to tidal waves. This project will set up a virtual organization for tsunami related data analysis using grid technology. Due to geologically remote areas/countries involved the sharing of seismic, tidal and other locally gathered tsunami related information is critical to issuing a warning. In collaboration with Australian and International partners, this project will explore: new avenues of tsunami-related data collection, which are currently not available; new data fusion methods; data sharing strategies; visualisation and analysis methods; and develop sensing methods to gather data on animal behaviours often reported as a possible way of identifying similar disasters.Read moreRead less
