Fire performance of concrete using novel fire testing. Thermal loading experienced by concrete samples in conventional tests cannot be accurately and independently controlled. This project, through using a novel thermal loading technique, aims to re-examine the performance of concrete in fire. By establishing the heat-flux as a parameter of study, concrete performance under a wide range of fire conditions is expected to be better quantified, eventually leading to a reliable performance-based des ....Fire performance of concrete using novel fire testing. Thermal loading experienced by concrete samples in conventional tests cannot be accurately and independently controlled. This project, through using a novel thermal loading technique, aims to re-examine the performance of concrete in fire. By establishing the heat-flux as a parameter of study, concrete performance under a wide range of fire conditions is expected to be better quantified, eventually leading to a reliable performance-based design of concrete structures. Expected outcomes include improved understanding of concrete performance under combined fire and other loadings, appropriate mathematical models for fundamental concrete properties and constitutive relations, and design recommendations for concrete performance under real fire exposures.Read moreRead less

Summary
Performance level structural testing facility. A structural testing facility is proposed for the new Advanced Engineering Building at The University of Queensland. The focus of the research supported by this facility will ensure the functionality of Australia’s infrastructure resources and the development of new engineering solutions that will enhance the country’s long-term economic growth.
Qualitative and quantitative modelling of hydraulic fracturing of brittle materials. Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and compu ....Qualitative and quantitative modelling of hydraulic fracturing of brittle materials. Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and computational investigations, aims to establish fundamental understanding of key processes controlling fracture formation in brittle materials (coal seams and porous rocks) under the action of hydraulic fracturing. The research outcomes will help to assess and minimise the risks associated with the hydraulic fracturing technology. Read moreRead less

Engineering the strength and consolidation of reclaimed soft soil. This project aims to strengthen reclaimed soft soils by controlled desiccation. Soft soil is a significant engineering challenge for many industry sectors in Australia and worldwide. The disposal of dredged soft soil is costly and time-consuming, and failure of soft mine tailings is an environmental catastrophe that can cause loss of life and interrupt mining production. This project will research the underlying processes of material behaviour, by developing new electromagnetic measurement and modelling methods to predict material strengths at the micro and macro scales during desiccation. The new approach is expected to lead to innovative solutions to bearing capacity and settlement problems associated with soft soils.Read moreRead less
