Unlocking self-healing bio-concrete through multiscale modelling. 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.

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
Novel Hydrophobic Concrete for Durable and Resilient Mining Infrastructure. The mining field is harsh with various corrosive media that cause rapid deterioration and ageing of concrete. This project aims to develop a novel hydrophobic concrete with integrated water-proofing and self-healing capacities and optimise its efficacy and cost-effectiveness for durable and resilient mining infrastructure using hybrid water-repellent nanoparticles and raw crystalline admixtures. The new hydrophobic concr ....Novel Hydrophobic Concrete for Durable and Resilient Mining Infrastructure. The mining field is harsh with various corrosive media that cause rapid deterioration and ageing of concrete. This project aims to develop a novel hydrophobic concrete with integrated water-proofing and self-healing capacities and optimise its efficacy and cost-effectiveness for durable and resilient mining infrastructure using hybrid water-repellent nanoparticles and raw crystalline admixtures. The new hydrophobic concrete is expected to significantly improve structural safety, durability, and service life of mining infrastructure while simultaneously reducing protection costs, repair needs, and reconstruction. The outcomes will offer desirable benefits for Australia’s mining industry, with significant reductions in maintenance costs.Read moreRead less
