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
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
Multi-functional nano-modified cementitious materials for well cementing. By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and n ....Multi-functional nano-modified cementitious materials for well cementing. By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and natural gas resources. Cementing problems are the main factor contributing to incidents during drilling and completion of wells, necessitating costly remediation. It is expected that the novel cement developed in the project will produce safer wells with fewer (gas) environmental emission risks.Read moreRead less

Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it r ....Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it represents the stress amplitude below which fatigue failures should not occur. Its existence in unnotched pipes and in the newer PVC materials is uncertain. This project will quantify fatigue thresholds and the mechanisms involved in crack initiation in uPVC , mPVC and oPVC.Read moreRead less

Magneto-optical materials have a wide range of potential applications in consumer products, telecommunications and defence. Nanotechnologies based on these materials offer an even broader range of emerging applications.

A study of the effects of severe plastic deformation by ECAP on the crystallographic anisotropy and the resulting microstructure-property relationships. The project will assist in improving the technology of manufacture of aluminium can body-stock, a large industry world-wide and help to keep Australian manufacture competitive with the overseas product. Because the Industry Partner has manufacturing activities in regional centres, it will also assist in strengthening regional industry.
Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specificat ....Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specifications. This is due to the limited understanding of wind-induced fatigue of cladding. This project will provide the framework for understanding and minimizing cladding fatigue. A realistic single test will also reduce cost and result in better design systems.Read moreRead less
