In a world-first project, the CRC for Low Carbon Living (CRCLCL) has partnered with NSW Ports to beneficially utilise co-products from coal-fired power stations and iron and steel manufacturing into low-carbon geopolymer concrete bollards to protect the coastline at Port Kembla from extreme weather events.
The predicted rise of the sea level, coupled with the increasing frequency of massive storms due to global warming has become a real issue for Australian coastline protection. Luckily there's a solution: Steel Furnace Slag!
Research from the Lawrence Berkeley National Laboratory in the USA shows the use of slag in pavements and roads is seen to reduce the heat island effect suffered by a lot of metropolitan areas, due to increasing the reflectivity of the finished pavement.
As geopolymer concrete knowledge increases, so does its interest. The increasing amount of research, technical and commercial papers being produced and published supports this view. Geopolymer concrete is becoming more widely accepted within the industry and in turn, the promotion the reduced CO2 benefits that come from displacing emission from Portland Cement.
This world first Geopolymer Concrete Handbook is designed to assist engineers and users in specifying and using Geopolymer concrete with greater confidence and less risk within the industry.
As the industry is very much aware, slag is a highly resourceful product. Hendrik G van Oss, a mineral commodity specialist for the U.S. minerals information center, agrees with this, rewarding iron and steel slag with the title of “Mineral Resource of the month” earlier this year while stating that iron and steel slags are co-products of iron and steelmaking, not waste products.
Another four years has past, the Rio de Janeiro Olympics have come and gone and the Australian Team managed to bring home eight Gold medals, eleven Silver and ten Bronze, overall taking out 10th place. Again, punching well above our weight for our relatively small population.
Concrete is the second most used commodity in the world and although its applications are great, its environmental impacts are distressing. With estimated 10% of all CO2 output being attributed to concrete production. there has to be an answer for this environmental conundrum.
All those educated about slag know that its benefits outweigh its flaws 10 to 1. To increase its use and applications it is important to share factual, positive stories about slag. Connections and Connections Selections do just that.
The issue of concrete cancer and erosion has become increasingly more common across Australia from the 1960’s. Since then the problem has only escalated and is now a widespread problem on Queensland’s east coast. This is because this area is prone to the three (3) major causes of Alkali-Silica Reaction (ASR) or concrete cancer.
After months of meticulous editing, QRG 4 - Electric Arc Furnance Slag is live and ready to read! The 4 page publication encompasses the physical properties, applications, environmental considerations and multiple case studies.
We want to know what you think about Connections and how we can improve it for you in the future. A short two minute survey is now avaliable online, we would love to hear your thoughts and ideas about future editions.
In the United States two researchers at DOE's National Energy Technology Laboratory have discovered that mixing two slag products at a unique ratio can generate energy in the form of heat and fuels.
The CRC: Low Carbon Living project commenced on the 12th of December 2012. Upon its initiation it was expected to create seven beneficial outcomes by 2020, including being able to provide 88 research students with detailed experience in the low carbon built environment. One of these 88 students (Jamie Watts) has recently produced his CRC funded Honours Thesis.
Australian technology which harvests molten iron blast furnace slag and converts it into a granulated blast furnace slag make cement is being trialled in China where 60% of the world’s iron blast furnace slag is produced. The process is considered environmentally within metal production, called Dry Slag Granulation (DSG), reduces water use and cuts greenhouse gas emissions.
The Cooperative Research Centre for Low Carbon Living approval for a $3.1 million project, RP1020: Reducing Barriers for Commercial Adaptation of Construction Materials with Low-Embodied-Carbon will span the next three (3) years and is well on track with progress to be reviewed in April 2015.
