Field investigation of biogenic corrosion of mortar specimens at North Head Wastewater Treatment Plant

This report outlines the results if a three-year study into biogenic corrosion of mortar in an aggressive environment. While concrete is one of the most widely used materials in the transportation and treatment of sewage, it is subject to rapid decay under in a sewage...

Development of high-density geopolymer concrete for breakwater armour units for Port Kembla Harbour

Coastal infrastructure is under constant attack from the marine environment. Under current conditions, breakwaters and seawall armoured by rock or concrete units require regular monitoring and maintenance. But with anticipated changes to the coastal wave climate due to climate change scenarios, costal structures would be...

Field performance of geopolymer concrete structures

A major barrier to the adoption of Geopolymer concrete in construction is the lack of long-term performance data. Field testing has been undertaken to determine the behaviour of geopolymers in different service environments and address the gaps in knowledge. The University of New South Wales...

Hybrid life cycle assessment of greenhouse gas emissions from cement, concrete and geopolymer concrete in Australia

Concrete is the second most used material after water and the production of cement is responsible for 5–8% of global carbon dioxide emissions. The development of low-carbon concretes is pursued worldwide to help the construction industry make its contribution to decarbonising the built environment and...

Carbonation of a low-calcium fly ash geopolymer concrete

The carbonation resistance of a blended slag and low-calcium fly ash (FA) geopolymer concrete was investigated. The geopolymer binder studied was composed of 90% low-calcium FA and 10% ground granulated blast-furnace slag. The alkalinity of the pore solution plays a pivotal role in carbonation progression...
