Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation ....Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation of results. While theoretical developments of this project are general, in the sense that they are not restricted to particular engineering disciplines, the four chosen applications closely align with two major research priorities namely An Environmental Sustainable Australia and Promoting and Maintaining Good Health.Read moreRead less

This project aims to develop an assessment model to accurately measure greenhouse gas emissions that roads generate over their life cycle. The project will integrate recent methodological developments and practical advances from road construction and maintenance into its proposed assessment model. The expected outcome will be an assessment model and mapping tool which will visualise emissions levels and better map these emissions into the cost-benefit analysis of roads. This will make greenhouse gas reduction more effective and cheaper, and make the Australian infrastructure sector more competitive.Read moreRead less
Modelling and testing corroding reinforced concrete structures. The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion.

The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction of both active steel reinforcement corrosion and the time to concrete cracking in a chloride environment. It then plans to develop a non-destructive method, combining ultrasonic waves-based technology and acoustic emission, to detect active steel corrosion before any damage is visible on the structure.Read moreRead less
