This project aims to formulate a new mix design for sustainable and resilient infrastructure materials with radically improved material properties and performance, as well as reduced life cycle cost and impact on the environment and societies. The aim of the project is to investigate the effect of dune sand and graphene oxide on mechanical properties and durability of concrete composites including properties and strength relation and alkali-silica reaction in concrete. The optimal mix design will be supported by the understanding of the interaction between graphene oxide, water molecules, dune sand and cement at nanolevel via scanning electron microscopy (SEM) and molecular dynamics simulations.Read moreRead less

Active rheology control of fresh concrete using responsive additives. This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages. ARC will also be useful to solve the major barrier faced by 3D concrete printing (3DCP) from becoming a ....Active rheology control of fresh concrete using responsive additives. This project aims to investigate innovative techniques for Active Rheology Control (ARC) of concretes using responsive additives interacting with externally applied electromagnetic or temperature signals. ARC is a new concept which will revolutionise concrete pumping by overcoming limitations such as frequent pipe blockages. ARC will also be useful to solve the major barrier faced by 3D concrete printing (3DCP) from becoming a practical way of construction. 3DCP is an emerging idea for construction but a major barrier is that concrete needs to flow during pumping and extrusion but become stiff soon after placement. This project will explore ARC for achieving the “flow-on-demand” desired by both concrete pumping and 3DCP applications.Read moreRead less

This project aims to develop an innovative polymer concrete composite system for the safe and efficient storage of hydrogen. New knowledge is expected to be generated on the novel use of polymer and concrete materials in hydrogen storage technologies. The expected outcomes include a new class of prefabricated, modular storage system that is highly efficient and low cost. The scalability and resilience of the system will be achieved by using concrete, a material widely used in the construction industry for its mechanical performance, durability and affordability. This should provide significant benefits in fostering the hydrogen economy by providing an efficient and resilient storage system for industrial quantities of hydrogen.Read moreRead less
Innovative composite systems with enhanced resilience to extreme loads. The rapidly increasing global population (projected to be 9.8 billion by 2050) and global urbanisation have created a demand for the construction industry, thereby increasing the pressure on our planet’s limited resources for the construction industry. This high demand can yield detrimental effects to the environment due to the high carbon footprint of conventional construction materials, and is amplified by the threat of ac ....Innovative composite systems with enhanced resilience to extreme loads. The rapidly increasing global population (projected to be 9.8 billion by 2050) and global urbanisation have created a demand for the construction industry, thereby increasing the pressure on our planet’s limited resources for the construction industry. This high demand can yield detrimental effects to the environment due to the high carbon footprint of conventional construction materials, and is amplified by the threat of accidental or deliberate extreme loadings to buildings, which can trigger fatal progressive collapse events. The proposed project aims to develop an innovative structural system with that possesses superior structural resilience to extreme loads and progressive collapse using lightweight eco-friendly materials.

Coupled effects of stress and temperature changes on concrete structures. The coupled effects of stress and temperature changes that concrete structures are commonly subject to are significant and need to be properly accounted for. However, existing engineering models accounting for these effects remain essentially empirical, necessarily limiting their predictive capability. This research aims to examine such coupled effects using an innovative approach combining original physical-based analytic ....Coupled effects of stress and temperature changes on concrete structures. The coupled effects of stress and temperature changes that concrete structures are commonly subject to are significant and need to be properly accounted for. However, existing engineering models accounting for these effects remain essentially empirical, necessarily limiting their predictive capability. This research aims to examine such coupled effects using an innovative approach combining original physical-based analytical study with novel tests and advanced numerical work. Expected outcomes include a robust yet simple engineering model, and guidelines for rational design of structures (incl. concrete spalling in fire) with due account for such coupled effects, thereby enabling to achieve more robust structures at substantial cost saving.Read moreRead less
