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 environment due to acids produced due to the action of...

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 (UNSW Sydney) and Swinburne University of Technology (SUT) undertook field...

A resistivity-based approach to indicate chloride permeability of geopolymer concrete
Chloride ion penetration in concrete is one of the major causes of deterioration of reinforced concrete structures by depassivation of reinforcing bars. Since testing of the natural chloride penetration is time consuming, utilising an accelerated test method is more desirable. Surface resistivity test is increasingly being used, due to its relative speed and ease of...

State of practice: high volume applications of fly ash and barriers to commercialisation
Australia is heavily reliant upon the use of coal for electric power generation with approximately 74.9% or 170,822 GWh of electricity in year 2010 to 2011 being generated through coal-fired power plants. Australia’s coal powered generators produce about 14 million tonnes of fly ash per year. Currently, only 42% of by-product fly ash is used...

Pathways for overcoming barriers to implementation of low CO2 concrete
As part of the CRCLCL Program 1: Integrated Building Systems, pathways for adoption of low CO2 concrete are being identified. The objectives of the research described in this report were to examine the current state of the art in the design and specification of concrete in Australia and consider how barriers to implementation of low...
