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

Summary
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 hi ....Foam concrete using three-dimensional printing and nano-engineering. This project aims to design foam concrete.

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

By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and natural gas resources. Cementing problems are the main factor contributing to incidents during drilling and completion of wells, necessitating costly remediation. It is expected that the novel cement developed in the project will produce safer wells with fewer (gas) environmental emission risks.Read moreRead less

Geopolymer technology transforms waste aluminosilicate materials into commercially viable products, which possess superior physical and chemical properties compared to ordinary concrete. These high-tech materials have novel acid and fire resistance applications, e.g. in construction and for the coating of optical fibres. Understanding the chemical relationship between geopolymers and other cementitious materials is pivotal to further advances in inorganic polymers. This project uses surface reactivity, spectroscopy, electronmicroscopy and electron diffraction to determine the role of calcium and cellulosic additives in the phase composition, microstructure and properties of geopolymers. Therefore, the factors distinguishing geopolymers from alkali-activated cement and ordinary concrete are identified.Read moreRead less
