Effect of processing on microstructure of 'Biocrete' organo-mortar. 'Biocrete' is a novel organo-mortar whose composition differs substantially from conventional Portland cement based polymer mortars. It is a relatively new product with significant commercial potential because of its acid resistance and ease of application. However, the microstructure of this material is extremely complex and not well understood nor is the way the microstructure develops during the processing and application of ....Effect of processing on microstructure of 'Biocrete' organo-mortar. 'Biocrete' is a novel organo-mortar whose composition differs substantially from conventional Portland cement based polymer mortars. It is a relatively new product with significant commercial potential because of its acid resistance and ease of application. However, the microstructure of this material is extremely complex and not well understood nor is the way the microstructure develops during the processing and application of the material known. This project will use advanced materials characterisation methods to elucidate the microstructure and to quantify the effects of processing parameters on the microstructure. Such information is critical for further formulation and application development in important areas such as sewer relining.Read moreRead less

The Australian automotive export market (vehicles, parts, engines) is worth approximately $4,500 million p.a. and is a major employer in many areas. A reliable, cheap and efficient method for preparing polymer surfaces for painting will significantly benefit that market. The ability to manufacture quality, cheaper, lightweight parts improves the competitiveness of the local automotive industry. More importantly, a technology for production of cheap, high quality painted polymer surfaces vastly improves the competitiveness of local component manufacturers who supply to international vehicle manufacturers. This project falls under the National Research Priority Area 'Frontier Technologies for Building and Transforming Australian Industries'.Read moreRead less
Development of PVC-Based Polymer Nanocomposites. The aim of the project is to develop a PVC polymer nanocomposite material to be used in water pipelines. It has been found that the inclusion of a nanoparticle phase, in this case calcium carbonate, leads to increases in strength, stiffness, toughness and abrasion resistance. This proposed project will develop and assess an optimum material in addition to investigating the mechanisms of deformation.
Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous ....Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous and complicated form of corrosion. Existing experience indicates that EAF incidence will increase as magnesium alloys are increasingly used in more challenging applications. The results and insights from this research will help to underpin a major new industry and industrial applications.Read moreRead less

Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of ....Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of the road asset exceeds $106,000 million. Thus providing satisfactory tough protective shield on asphalt pavements that locks out destructive elements and provide long-term protection is of enormous economic importance and national/community benefit.Read moreRead less
Next generation chromium free primers for galvanised steel. This project aims to develop a new family of chrome-free primers to protect galvanised steel against corrosion. Corrosion resistance is a critical factor in durability of galvanised steel, which is usually protected from corrosion by a primer and topcoat, which prolong life and provide aesthetics. The primer coating contains chromates. Chromates are recognised for their toxicity, but in spite of this they unfortunately remain the indust ....Next generation chromium free primers for galvanised steel.

Corrosion resistance is a critical factor in durability of galvanised steel, which is usually protected from corrosion by a primer and topcoat, which prolong life and provide aesthetics. The primer coating contains chromates. Chromates are recognised for their toxicity, but in spite of this they unfortunately remain the industry standard. Chromate-free primers are urgently required, and this project aims to conduct fundamental research to enable their development.Read moreRead less

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.

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
