Summary
Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring tog ....Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring together a multi-disciplinary team with complementary strengths to provide an integrated solution for rehabilitation of structures. The core of the network focuses on design tools, linking the various technologies to provide appropriate rehabilitation and understanding of life cycle demands for major infrastructure.Read moreRead less
Self-Healing Concrete for Mitigation of Chloride Induced Steel Corrosion. This project aims to develop an intrinsic self-healing concrete using crystalline admixtures for rapid healing of concrete cracking. In marine environments, concrete cracking provides a direct access for chlorides from sea water to the steel reinforcement, leading to early and severe steel corrosion. The self-healing concrete will be designed to address the two main causes of concrete structures deterioration in Australia: ....Self-Healing Concrete for Mitigation of Chloride Induced Steel Corrosion. This project aims to develop an intrinsic self-healing concrete using crystalline admixtures for rapid healing of concrete cracking. In marine environments, concrete cracking provides a direct access for chlorides from sea water to the steel reinforcement, leading to early and severe steel corrosion. The self-healing concrete will be designed to address the two main causes of concrete structures deterioration in Australia: early age cracking due to restrained shrinkage and chloride induced steel reinforcement corrosion. The outcomes of this project will drive the advances in developing and applying crystalline admixture-based self-healing concrete to extend the service life of concrete structures and avoid costly repair.Read moreRead less
Long-term behaviour of thin-walled concrete curved members strengthened with externally bonded composite materials. Concrete arches and domes are prone to catastrophic failures which involve loss of life and limb, and many global iconic structures are of this form. When subjected to creep, shrinkage and thermal effects, their behaviour is non-linear and complex. This proposal will keep Australian research at the forefront by developing a fundamental understanding of these structural forms over t ....Long-term behaviour of thin-walled concrete curved members strengthened with externally bonded composite materials. Concrete arches and domes are prone to catastrophic failures which involve loss of life and limb, and many global iconic structures are of this form. When subjected to creep, shrinkage and thermal effects, their behaviour is non-linear and complex. This proposal will keep Australian research at the forefront by developing a fundamental understanding of these structural forms over time, when strengthened with externally-bonded composite materials in an innovative retrofit procedure. It encompasses the priority goal of frontier technologies for building and transforming Australian industry, will lead to valuable guidance for engineers, and will contribute to the training of skilled PhD scholars.Read moreRead less

Fibre Reinforced Polymer (FRP)-Confined Concrete-Encased Steel Composite Columns. The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns.

The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.

Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and saf ....Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and safe applications of these columns in the construction of resilient and sustainable infrastructure, the project will enable expansion of the domestic and worldwide market for Australian producers of geo-polymer concrete and fly ash aggregates.Read moreRead less
Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in struct ....Maximising the Use of Waste Glass in Sustainable Composite Columns. This project aims to develop novel structural concrete made with over 80% waste glass for use in manufacturing sustainable concrete-filled steel tubular columns used in buildings. Because of limited established markets for recycled glass, significant stockpiling of recycled and recyclable waste glass currently exists across Australia. This study will provide a suite of novel solutions to maximise the use of waste glass in structural concrete by fully replacing sand and gravel with crushed glass and up to 72% cement with glass powder. This will provide practical solutions to address not only Australia's glass recycling crisis but also the worldwide issue of disposal of waste glass.Read moreRead less

The project provides a comprehensive physical understanding on thermal de-consolidation and re-consolidation processes in advanced thermoplastic composites during re-heating/cooling processes, such as thermoforming and joining. Mechanistic models based on theoretical analysis, experimental studies and computational modelling will be established to provide a unified approach to predict de-consolidation and re-consolidation processes. Optimum processing-windows will be established, with which the undesired deterioration in material meso-structures and mechanical performance due to de-consolidation is effectively minimised. The outcomes of the project will fill the gap in the knowledge for thermoplastic composite processing and will improve the integrity of thermoplastic composite structures in practical applications.Read moreRead less
