Conventional concrete is made using fresh water and river sand. This project aims to develop a novel hybrid construction system using seawater, sea sand and industrial waste, together with fibre reinforced polymer (FRP) and stainless steel (SS), for use in civil engineering infrastructure in marine environments. To date there has been little work to understand the degradation kinetics and mechanisms of FRP and SS in such complicated corrosive environments. The project plans to provide a design methodology to ensure confidence in the safety of critical infrastructure such as bridges, highways, dams, airports, offshore piles and artificial islands. The proposed system would save fresh water and reduce damage to river ecosystems, carbon dioxide emissions and construction costs.Read moreRead less

Building resilience in wastewater infrastructure with self-healing bioconcrete. This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater.

This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater. The bacteria, added to bio-concrete, can fill cracks or reseal corroded areas by using organic substrates from wastewater to generate concrete, thus maintaining structural strength and preventing further damage. This project is expected to enhance the resilience and sustainability of wastewater infrastructure in ever more demanding environments.Read moreRead less
A novel method for controlling microbial concrete corrosion in sewers. This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role.

This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role. The technology will be designed to prevent corrosion of new concrete sewers by adding a precursor chemical into the cement, or to slow down the corrosion of existing sewers by infrequently (once every one to few years) spraying the precursor chemical directly onto the concrete surface. Potentially, the project will substantially reduce sewer corrosion.Read moreRead less

This project aims to develop an integrated prefabricated building panel solution combining green wall and hempcrete technology to address environmental problems associated with the usage of carbon intensive construction materials, dense urbanisation, climate change and biodiversity. Innovation in hempcrete technology consist in using low carbon options including alkali-activated binders and biomineralization technology, glass waste replacing natural sand. Hempcrete green wall panels will be design to be carbon positive, improve the thermal performance of buildings, provide better acoustic insolation, reduce the risk of mould proliferation, control indoor humidity and air quality and improve indoor thermal comfort.

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
Paving the way: an experimental approach to the mathematical modelling and design of permeable pavements. The intelligent use of permeable pavements will enable restoration of degraded land corridors. Collection and treatment of stormwater via filtration through porous media will improve water quality in urban environments and will also control flooding. The integration of ecology and urban living will present a revolutionary way to revitalize cities.
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: 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
