This project aims to address the challenges of field applications and commercialisation of biocementation technology. Biocementation is the process through which Nature, with the help of microbes builds large and durable carbonate formations such as corals and beach rocks. This is emerging as a clean technology that alleviates the sustainability challenges faced by the construction industry. Microorganisms especially suited to Australian conditions will be developed focusing on optimum use of resources for economic and environmental viability. Biocementation products will be developed for easy field application and self-healing concrete and bioremediation will be attempted on deteriorated structural systems. This technology has the potential to usher in the era of biologisation of construction.Read moreRead less

Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes) ....Concrete Enriched with Carbon Nanotubes for Advanced Future Construction. This project aims to develop an advanced construction material based on enrichment of concrete with carbon nanotubes (CNT). Concrete, the most consumed construction material globally, is brittle and needs embedded steel reinforcement. Concrete enriched with CNT, one of the strongest known fibres, may partially replace conventional bulky and heavier steel reinforcement thereby creating economies (e.g. thinner section sizes), and reduced carbon dioxide emissions by expending less steel and cement for construction. This project extends earlier research by the research team and aims to transform cement-CNT pastes into construction-scale concrete by resolving uncertainties associated with scaling.Read moreRead less
Development of ambient cured high performance geopolymer composite. The project intends to develop an ambient-cured high-performance, sustainable, fibre-reinforced geopolymer composite for construction. Compared to cement, which is currently used extensively in the construction industry, production of the geopolymer material not only recycles industry wastes which would otherwise end up in landfills, but also consumes less energy and emits significantly less greenhouse gases into the atmosphere. ....Development of ambient cured high performance geopolymer composite.

Compared to cement, which is currently used extensively in the construction industry, production of the geopolymer material not only recycles industry wastes which would otherwise end up in landfills, but also consumes less energy and emits significantly less greenhouse gases into the atmosphere. The composite is also designed to have a higher strength and deformation ability than cementitious material. The project plans to perform intensive experimental tests to determine the optimal mix for the best performing material, and develop material and numerical models to predict the responses of structures made from the composite when subjected to static and dynamic loads.Read moreRead less

Self-healing bio-concrete, which uses bacteria as means to repair cracks, has the potential to revolutionise the construction industry and reduce the infrastructure repair and maintenance cost by billions of dollars annually. To unlock this, we need to understand the bacterial self-healing mechanisms for effective control of the performance. This project will develop a multiscale framework to describe the competing mechanisms between crack widening and healing at the macro-scale, incorporated with key information of substances diffusion and bio-cementation at the meso- and micro-scales. This will enable to optimise the self-healing of bio-concrete via design–test–learn approach and enhance the durability of structures under sustained loads.Read moreRead less
