Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual defl ....Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual deflection leading to serviceability problems. The significance of this investigation hence lies in its potential to provide a solution to more accurately predict service-life deflections in post-tensioned concrete suspended slabs and validate the model with real-life deflections monitored over time on a current building project.Read moreRead less
Securing Longevity of Reinforced Concrete Infrastructure Through Enhanced Cathodic Protection Design. The sustainability of Australia's extensive maritime infrastructure is impaired by corrosion, causing ongoing rehabilitation and reduced service life. Cathodic protection (CP) is most widely used to restore corrosion-damaged concrete, however the design principles are debated and uncertainty exists on how ongoing performance should be monitored. Australian Industry will benefit from: (i) Less ex ....Securing Longevity of Reinforced Concrete Infrastructure Through Enhanced Cathodic Protection Design.

Carbon nanotube fluidic channels for desalination - interplay of nanoscale confinement and electrostatics. Tiny tubes of carbon, ten thousand times smaller than human hair, allow water to pass through at extraordinary speed. This project aims to understand and improve their salt rejection properties using comprehensive experimental and theoretical approaches. This will provide the impetus and knowledge for developing advanced membranes for desalination
A New Approach to Advanced Steels via Cluster and Precipitate Strengthening. Formation of interphase nanoparticles and clusters is a new approach to increase strength in advanced high strength steels. Exceptionally high strength levels can be achieved in alloys that only have solute clusters by controlling the temperature-time history. However, the exact mechanism for the formation of clusters and precipitates and the cluster strengthening mechanism are not understood, nor do we know how to cont ....A New Approach to Advanced Steels via Cluster and Precipitate Strengthening. Formation of interphase nanoparticles and clusters is a new approach to increase strength in advanced high strength steels. Exceptionally high strength levels can be achieved in alloys that only have solute clusters by controlling the temperature-time history. However, the exact mechanism for the formation of clusters and precipitates and the cluster strengthening mechanism are not understood, nor do we know how to control cluster formation. This project aims to develop a fundamental understanding of the formation of clusters and nanoprecipitates and determine their contribution to strengthening and other mechanical properties using advanced characterisation techniques such as atom probe tomography and electron microscopy.Read moreRead less
Advanced high strength steels produced by energy efficient direct strip casting. Over one billion tonnes of steel is produced every year and one method of reducing the environmental footprint of this production is through strip casting. This process reduces the energy required to process liquid steel into thin sheet product by an astounding 90 per cent. This proposal aims to expand the application of this technology to new steel grades.

Carbon fibre composites, where carbon fibres are embedded in a polymer matrix, are gradually replacing traditional materials such as steel. For example, composites make up 50 per cent of Boeing’s 787 Dreamliner, resulting in a 20 per cent improvement in fuel economy. There is significant scope for improving the damage tolerance of these materials. A fundamental lack of understanding around the fibre matrix interface currently limits the development of new composite systems to overcome the problems with damage tolerance. This project takes inspiration from nature to develop a fundamental understanding of the interfaces within carbon fibre composites and optimise their behaviour via model-guided surface and interface engineering.
