Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age crack ....Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age cracking caused by shrinkage. The proposed research will investigate ways of using the new binder system to overcome these weaknesses and to reduce carbon dioxide emission. The expected outcome will be a proven technology for manufacturing new building materials that are environmentally more sustainable and with enhanced properties.Read moreRead less

INVESTIGATION OF THE MECHANISM CAUSING SHRINKAGE STRAINS IN CONCRETES MADE WITH SLAG BLENDED CEMENTS. Slag, an industrial by-product, can partially substitute portland cement. High slag contents produce highly durable concretes and help reduce the CO2 emissions due to cement manufacture. Major problem of high slag content is often the high shrinkages resulting in the concrete. This project will systematically study all the factors affect the shrinkage behaviour in slag-blended cement concrete ....INVESTIGATION OF THE MECHANISM CAUSING SHRINKAGE STRAINS IN CONCRETES MADE WITH SLAG BLENDED CEMENTS. Slag, an industrial by-product, can partially substitute portland cement. High slag contents produce highly durable concretes and help reduce the CO2 emissions due to cement manufacture. Major problem of high slag content is often the high shrinkages resulting in the concrete. This project will systematically study all the factors affect the shrinkage behaviour in slag-blended cement concretes including the appropriateness of the standard shrinkage measurement method. The other aim is to develop a micro-mechanical model to understand the fundamental mechanism involved. This model will also lead to a better understanding of the mechanisms involved in shrinkage in all concretes.Read moreRead less

Summary
Innovative risk analysis, assessment, rehabilitation and strengthening of aging critical civil infrastructure. Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community.

Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community. Australia is not spared by the ramifications of its aging civil assets, and identification and rectification procedures that are often ad-hoc now represent a sizeable proportion of the GDP. This Research Network draws together the leading Australian research groups in engineering and applied mechanics in a coordinated program to address this most important cost to the community.Read moreRead less
