Tensile enhancement of cements utilising carbon nanotubes to create stronger, lighter, more ductile, and easier-to-build structures. Portland cement, commonly used worldwide for construction, is brittle and prone to cracking. A carbon nanotube-cement nanocomposite will be developed, improving tensile strength and durability. Stronger and lighter structures are viable. Less cement (and steel reinforcement) will be needed, thus reducing CO2 emissions and promoting sustainability.

The project aims to develop high performance concrete structures using 3D printing techniques. 3D printing of concrete is receiving increasing attention because of its potential use for direct construction of buildings and other complex infrastructures of considerable dimensions and of virtually any shape. This project aims to develop high-performance concrete structures reinforced by multiscale (nano- and micro-fibre) fillers using 3D printing. The project plans to introduce a micro-fibre 3D mesh into the concrete with a ‘knitting’ technique. The outcome of the project may lead to a 60 per cent reduction in current manufacturing cost and reduction of the lead-time for concrete infrastructures.Read moreRead less

Foam concrete using three-dimensional printing and nano-engineering. This project aims to design foam concrete. Foam concrete, made of air-voids and thin concrete films, has good thermal insulation/fire resistance and energy adsorption capacity but is weak.

This project will develop a foam concrete via 3D printing to control air-void structures to achieve high strength and ductility and nano-engineering to improve the performance and durability of thin concrete films. It is expected that this high-performance foam concrete can be used as a load-bearing structural element to reduce construction costs. The project should discover chemical and physical mechanisms governing the resilience and sustainability of newly developed foam concrete.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
