This project will establish an effective and efficient computational framework for the topological optimisation of composites whose constituent phases possess significantly different Poisson ratios. In particular, the proposed research will be focused on exploiting the dramatic improvements in functional properties of composites when the Poisson ratio of one of the constituent phases is either negative or near its incompressibility limit. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of a new class of composites with exceptional properties. Such new composite systems will have many potential applications, particularly in aerospace, defence and medical industries.Read moreRead less

Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted.

Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix concrete industry with a “green” product for the residential construction market. Expected benefits include the increased use of a waste resource (used tyres), reduced use of a scarce natural resource (sand), and the development of an economic but green alternative concrete option for residential builders and owners.Read moreRead less

Three-dimensional concrete printing is a process for construction automation, and adapting recent advances in Additive Manufacturing technologies makes rapid progress possible. However, unsuitable concrete and structural designs and a lack of underpinning material and structural research hamper development. The project will test material properties, fabrication technologies and structural design concepts; and build and test freeform concrete structures. Achieving construction automation is expected to reduce injury rates by eliminating dangerous jobs, create high-end technology-based jobs, and make concrete construction cheaper by eliminating formwork.Read moreRead less

Thermal-induced unilateral plate buckling of concrete pavements: design and evaluation. The project addresses the upheaval buckling of concrete pavements, which is caused by increasingly frequent heat spells. It will consider both the vulnerability assessment of existing pavements, and the design of new pavements made from low-carbon geopolymer concretes (which are lighter than conventional pavements) against upheaval buckling.
