This project aims to develop next generation construction of multi-hazard resilient structures for the safety and wellbeing of the public, society and economy, as well as structural health monitoring techniques for effective engineering asset management. Sustainable infrastructure development involves the use of green materials to reduce greenhouse gas emission, and new technologies to reduce construction and life-cycle maintenance cost. The project will use new green materials and techniques to prefabricate structural components which can be easily assembled and dismantled to meet the requirement for adaptation to technology advancement, urban planning and climate change. The project will advance the construction practice for sustainable infrastructure development.Read moreRead less
Microplane material models for graphene-oxide-reinforced concretes. A material model for graphene based cement and concrete composites will be developed using state-of-art theoretical and experimental tools to understand the role of the nano level reinforcement. The model is necessary for the optimisation of these innovative sustainable materials for structural applications.
Novel cement-graphene oxide composite: understanding its composite structure via nano-mechanics based modelling and experimental tests. A high performance cement composite will be developed to reduce the usage of cement, and steel reinforcement, thus decrease carbon dioxide emissions, reduce labour costs, and promote sustainability. Modern modelling techniques will advance the knowledge in cement and concrete field and maintain the leading position of Australia.

State-of-the-Art Facility for Non-destructive Testing of Concrete Infrastructure (N-DETECT). State-of-the-art facility for non-destructive testing of concrete infrastructure: There are many recent examples around the world where ageing concrete infrastructure has led to catastrophic failures with loss of life and severe damage to infrastructure. Non destructive testing (NDT) gives a reliable method to provide an accurate assessment of the condition of a structure.

State-of-the-art facility for non-destructive testing of concrete infrastructure: There are many recent examples around the world where ageing concrete infrastructure has led to catastrophic failures with loss of life and severe damage to infrastructure. Non destructive testing (NDT) gives a reliable method to provide an accurate assessment of the condition of a structure. However NDT requires an understanding of the various methods available, and their capabilities and limitations, through systematic research projects. Very little research has been done in Australia and overseas in this area due to lack of facilities. This state-of-the-art testing equipment will provide Australian institutions with a cutting edge facility with portable equipment for NDT related research.Read moreRead less
Development of Steel Fibre Reinforced Concrete (SFRC) material with spiral-shaped fibres. This project will develop new spiral-shaped steel fibres to be added in concrete to improve its strength, toughness, crack bridging, deformation and impact resistance capacities. It will create better concrete material for wide applications in construction to resist extreme loading conditions such as explosions and high-speed impacts.
Nonlinear long-term behaviour and analysis of high strength concrete panels. This project investigates the nonlinear long-term response of high-strength concrete panels. As these panels find widespread use in many civil and industrial engineering applications, the outcomes of this project will enhance the understanding of their long-term behaviour and will provide a theoretical basis for their analysis and design.
Time-dependent behaviour of precast concrete sandwich panels. This project seeks to improve understanding of the long-term structural behaviour of precast concrete sandwich panels and thus facilitate their use in civil engineering applications. These panels offer many advantages over traditional concrete panels mainly due to their excellent thermal insulation and their use in civil and industrial engineering applications is expanding. Nevertheless, the literature reveals a lack of confidence in ....Time-dependent behaviour of precast concrete sandwich panels. This project seeks to improve understanding of the long-term structural behaviour of precast concrete sandwich panels and thus facilitate their use in civil engineering applications. These panels offer many advantages over traditional concrete panels mainly due to their excellent thermal insulation and their use in civil and industrial engineering applications is expanding. Nevertheless, the literature reveals a lack of confidence in their design due to the absence of reliable numerical models and test data of their long-term structural behaviour. This project aims to provide insight into the nonlinear long-term behaviour of such panels by developing new theoretical models that will be validated by laboratory testing.Read moreRead less

Active rheology control of fresh concrete using responsive additives. This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages.

This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages. ARC will also be useful to solve the major barrier faced by 3D concrete printing (3DCP) from becoming a practical way of construction. 3DCP is an emerging idea for construction but a major barrier is that concrete needs to flow during pumping and extrusion but become stiff soon after placement. This project will explore ARC for achieving the “flow-on-demand” desired by both concrete pumping and 3DCP applications.Read moreRead less

The project aims to develop a new rheological model for 3D printable concrete for construction. 3D concrete printing is an innovative and promising construction technique, but the main impediment to progress is lack of suitable material technology. In this study, a new stress and time dependent flow model will be formulated and implemented as a computational model. The model will facilitate the study of the effect of different concrete formulations, pumping and printer parameters on the primary printing properties, namely, pumpability, extrudability and buildability. The new model will also enable active control and modification of rheological parameters on-the-fly during large-scale printing, which is not currently possible.Read moreRead less
