Mixed Mode Torsion-Shear-Bending Failure in SFRC Elements . In 2017 and 2018 the Australian Standards for the design of concrete bridges and structures were released; these are some of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for shear and bending of SFRC girders, the rules exclude the use fibres to carry torsional moments.

Summary
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 investigate the effects of binder quantity and composition on early-age cracking in Australian concretes caused by restrained shrinkage, the subsequent self-healing capability of the cracks, and the possibility of detrimental early chloride induced steel reinforcement corrosion, particularly in marine locations. This project will focus on concrete mix designs and the blends of cement, fly-ash and blast furnace slag that are prescribed in the revised version of the concrete bridge standard for the most severe exposure. This project will lead to a significant improvement in the serviceability and durability of concrete structures in severe environments.Read moreRead less
