Editorial

Welcome back to another edition of Connections, we hope you’ve had a productive start to 2019. The Australasian (iron & steel) Slag Association have certainly been off to a busy start to the year, with a number of key member projects underway such as major road and intersection upgrades, and the Cooperative Research Centre for Low Carbon Living (CRC-LCL) projects wrapping up. The ASA’s involvement demonstrates the continued investment and commitment to furthering the beneficial outcomes associated with the use of iron and steel slags.

The ASA conducts an annual survey for information regarding iron & steel slag production and sales by members and nonmembers for each calendar year. The Association has provided a brief overview and commentary on the statistics and figures returned by our survey participants in regard to their annual production and sales of iron and steel slags (ISS). The 2017 Survey Report is available on page 2 for your convenience.

This edition features contributions from a number of Association members about recent projects they have been involved in. We spoke to Australian Steel Mill Services (ASMS) to find out about their involvement in the major intersection upgrade at Botany Road and Wentworth Avenue as part of the Airport East and Airport North Projects, supplying over 1800 tonnes of RBM800 Slag Road Base. Also, SLN have announced that Ferronickel slag (FNS) has arrived in Port Kembla and is now available for use in Australia.

Researchers from UOW have recently published a paper in the Journal of Building Engineering, which develops a simple and practical method to quickly find the optimum mix design of geopolymer concrete cured in ambient condition. As part of their research, they used Ground Granulated Blast Furnace Slag (GGBFS) supplied by the ASA. The authors’ have given Connections readers insight into their paper and research.

The ASA has been involved in a number of recent industry events, with our Executive Director, Craig Heidrich, attending Construction Materials Industry Conference, CIA/FIB Conference, Steel Stewardship Council Annual Meeting, CRC for Low Carbon Living's Annual Participants’ Forum, Combined Australian Materials Societies Symposium and Zero Carbon Concrete Working Group Workshop. There’s no slowing down on the horizon for the industry, with a number of upcoming conferences throughout the rest of 2019. The event calendar presents a number of these important industry events with information on how to get involved and register.

Finally, the Australasian (iron & steel) Slag Association would like to thank all readers of Connections for your commitment and support to iron and steel slags beneficial use. We are always on the lookout for content for future editions, so if you think you have a relevant story, event or upcoming project, we would love to hear from you!

2017 MEMBERSHIP SURVEY RESULTS:

JANUARY - DECEMBER

The Australasian (iron & steel) Slag Association (ASA) conducts an annual survey for information regarding iron & steel slag (ISS) production and value-added sale of slag quantities by members and non-members for each calendar year. This report, compiled during 2018, reports on industry members1 and non-members’ ISS production, importation and sales for the calendar period 2017.

Information provided by members and non-members is reviewed, compared, collated and aggregated into a national set of results and includes ISS production levels by nominated uses for all slag products.

THE KEY RESULTS FOR THE CALENDAR PERIOD 2017 SURVEY WERE:

2.8

For the calendar period January to December 2017, some 2.521 million tonnes (Mt) of iron and steel slag produced nationally, combined with imported ISS from overseas sources, was used within various sectors. Compared with 2016, there was a modest increase of approximately 70,000 metric tonnes of slag used within select markets.

2.5 105 1.5 0.8 0.2

MILLION TONNES OR 91% WAS EFFECTIVELY UTILISED FROM THE ISS AVAILABLE

The ongoing increase in the volume of ISS and slag utilisation continues to correlate well with demand for steel and the increased road and infrastructure spending by the Australian Government, in particular within the streams of steel production for BOS and EAF processes. However, a minor reduction in demand for granulated blast furnace slag (GBFS) within the cement and concrete sectors has meant that GBFS use has decreased some 80,000 tonnes over the period. For the reported period, GBFS was from either domestic sources or imported mainly from Japan.

From the 2.774 Mt available, 2.521 Mt or 91% of ISS produced was effectively utilised within various value-added civil and construction material applications throughout Australasia.

In summary, the longer-term trend of ISS materials end use applications has stabilised its movement towards HVA away from LVA applications. To this end, the active recovery and use of ISS continues to provide significant positive environmental impacts, including resource conservation and in this case, the reduction of greenhouse gas emissions from the processing of virgin resources.

MILLION TONNES OR 30% WAS USED IN NON-CEMENTITIOUS APPLICATIONS

MILLION TONNES OR 10% WAS USED IN GENERAL, CIVIL OR FILL APPLICATIONS

Table 1 provides more detail for individual category sales of ISS for the period 2017 with comparisons against 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009 and 2008.

COOPERATIVE RESEARCH CENTRE FINAL MONTHS FOR LOW CARBON LIVING 2012 - 2019 As this edition goes to print, our team of researchers, industry partners and collaborators will have undertaken our third major demonstration project in partnership with the City of Sydney Council. We decide to have a Q&A with the Craig Heidrich about the project.

Q. Why is the project important?

This project builds on the backbone and success of our previous projects of the Geopolymer Scoping Studies, Manufactured Aggregates, Durability Evaluation, Geopolymer Handbook and NSW Ports Sea Wall trails. In mid-2018, and as a direct outcome of the Handbook for Specification and Design of Geopolymer Concrete, this succeeding project embeds the outcomes of this work with large scale demonstration applications in geopolymer concrete pavements. Working with industry partners City of Sydney, Ash Development Association, and the Australasian (Iron & Steel) Slag Association, large pavement sections in Sydney will be cast, using knowledge generated in the Geopolymer Handbook, and monitored for performance.

Q. How does the project help end-users develop policy and industry?

The adoption of new or different materials for construction has been examined extensively by our Cooperative Research Centre for Low Carbon Living researchers, each highlighting the; technical, regulatory, economic and supply chain barriers specific to widespread commercialisation of geopolymer concrete.

Q. What barriers are being addressed?

Barriers are being addressed through this project as an example of large-scale demonstration projects in highly visible and well monitored demonstration sites. Specifically, the project will showcase through delivery by a major Australian council, and

www.asa-inc.org.au

Industry Partner City of Sydney, the adoption of Geopolymer concrete as “conventional” practice and a viable replacement for cement-based pavements. The project meets the City of Sydney stated objectives for “Sustainable Materials in Concrete”.

Q. What are the benefits to the Australasian (iron & steel) Slag Association?

The benefits to our Associations involved, namely the ASA and the Cooperative Research Centre for Low Carbon Living are multifaceted. We anticipate our investment and collaboration with organisations such as Ports NSW and City of Sydney, leading to the publication of our learnings about geopolymer concrete research in the public domain will only further de-mystify and promote the wider specification and use of geopolymer concrete.

Q. What are the advantages of Geopolymer Concretes?

From an industry perspective the advantages we see for the use of geopolymer concretes relate their; engineering properties, durability, performance, energy reduction and low carbon footprint when used in construction applications.

Q. What has the Association invested in this project?

It's a fundamental tenet in business that you need to be constantly innovating and investing into new technologies. The Cooperative Research Centre for Low Carbon Living has provided a platform to engage with research organisations, supply chain participants and partner with end user organisations such as Ports NSW and City of Sydney and deliver real examples of geopolymer concrete use.

GRANULATED BLAST

FURNACE SLAG

FOR THE WIN

Every four years, the fib Awards for Outstanding Concrete Structures are presented at the fib Congress. The 2018 awards were announced in Melbourne in October. The Award categories were ‘Buildings’ and ‘Civil Engineering’, which aimed to increase international recognition of concrete structures and the versatility of concrete.

Among the 2018 winners was a residential building in Tokyo, Japan by R.Torso.C. The mix design consisted of Granulated blast furnace slag cement, as well as limestone macadam, limestone sand and Shirasu, a fine aggregate, to make the mix 100% recyclable, strong and durable.

Shirasu, volcanic ash found in abundance in the south of Japan, had been used previously in civil engineering, but never before for architectural concrete. The material’s durability increases over time, has deodorising and humidity-controlling qualities and is environmentally friendly.

Caption: R. Torso C., Residence, Tokyo, Japan.

The building was designed with exposed concrete for both the interior and exterior of the home. All columns and walls maintain a thickness of 220mm – a huge challenge given the polyhedron form. The home is situated on a 66m2 (711 square foot) site and was extended vertically to maximise the space, with a triangular window used as a skylight.

SYDNEY'S AIRPORT EAST PROJECT CALLS ON ASMS SLAG ROAD BASE Australian Steel Mill Services (ASMS) recently took part in a major intersection upgrade at Botany Road and Wentworth Avenue east of Sydney Airport – one of Sydney’s busiest precincts, supplying over 1800 tonnes of RBM800 Slag Road Base.

The rebuilt intersection ties in with the new Wentworth Avenue underpass, which replaced the General Holmes Drive rail level crossing, to link General Holmes Drive, Botany Road and Wentworth Avenue.

“This was quite a unique and challenging project,” according to Gavin Tory, ASMS Manager, Sales and Business Development.

“The entire intersection was rebuilt over one weekend after many months of planning and coordinated by the civil contractor, John Holland Group together with numerous carefully chosen partners, including ASMS”.

The works included: • Removing the existing road surface • Excavating down to the new road level to facilitate access under a newly-constructed rail overpass, removing over 5,000 tonnes of materials and dealing with contaminated fill • Relocating services • Rebuilding the pavement using ASMS RBM800 road base • Laying new asphalt and line marking • Installing temporary traffic lights and signage The rebuild was completed over a weekend in February 2019 to minimise disruptions in the area. The plan called for a resumption of normal traffic flows for the peak period on Monday morning. The quick turnaround was a key priority in such a crucial intersection between Sydney Airport and Port Botany, with over 150,000 people travelling to and from the Airport precinct daily.

The work is part of the larger Airport East and Airport North projects, where ASMS is a key supplier to the upgrade of roads and intersections to improve traffic flow and access to and from Sydney Airport, Mascot, Port Botany, Eastern Suburbs and the future WestConnex Motorway.

www.asa-inc.org.au

Why ASMS RBM800 Slag Road Base?

ASMS RBM800 is a high quality, heavily bound road base used in a variety of rigid pavement applications. The blend of graded air-cooled blast furnace slag and granulated blast furnace slag modified with a slag cement/lime binder.

In this case, RBM800 was chosen as it has a demonstrated history in Sydney Airport and RMS works of being trafficable within a very short period after placement. In this example, placement of the road base commenced from 4 am on the Saturday morning with asphalting the following day, reopening to traffic for the Monday peak.

Unique properties of the RBM800 road base that facilitated this approach include its inherent cementitious properties and interlocking particle shape, ease of compaction and long-term strength gain. RBM800 also has the potential to reduce asphalt layer thickness in select applications and is an effective utilisation of an industrial by-product conserving natural resources.

ASMS is an important founding member of Australasian (iron & steel) Slag Association (ASA), established in 1990. They have since preserved their vital role in the Association. Gavin Tory, ASMS Manager, Sales and Business Development, is currently Chair of the ASA Management Board.

A NEW SIMPLE & FAST TEST METHOD FOR OBTAINING THE OPTIMUMHAIOUI MIXZHANG,DESIGN OF SHELLEY PARKINSON GEOPOLYMER CONCRETE & MUHAMMAD N.S. HADI Researchers from UOW recently published a high-quality paper (Optimum mix design of geopolymer pastes and concretes cured in ambient condition based on compressive strength, setting time and workability) in the Journal of Building Engineering, which develops a simple and practical method to quickly find the optimum mix design of geopolymer concrete cured in ambient condition. This new simplified method could improve the application of geopolymer concrete, which was recognized as a green building material.

In this paper, at first, a series of small scale geopolymer paste tests were conducted to find the optimum mix design. It was found that the properties of the geopolymer paste under optimum mix design were better than those of ordinary Portland cement (OPC) pastes. Then the geopolymer concrete tests based on this optimum mix design were carried out, which is used to ensure this optimum mix design can also be applied to concrete.

It was found that the properties of geopolymer concrete based on optimum mix design of geopolymer paste were also better than the properties of OPC concrete. Therefore, it is certain that the geopolymer concrete based on optimum mix design of geopolymer paste can replace OPC concrete. This method can help engineers save a large amount of time and labour to find the optimum mix design of geopolymer concrete, and to ensure it can replace OPC concrete.

www.asa-inc.org.au

Lastly, the multivariable regression models based on polynomial equations were proposed to predict the 28-day compressive strength, initial setting times and mini slump test results.

This model was easy to be used by engineers. All the tests were conducted in the ambient condition, which could save a lot of energy and become more practical on site. Also, the aluminosilicate materials used for geopolymer concrete were slag and fly ash, which were waste materials supplied by the Australasian Slag Association and Eraring power station. This study may improve the application of geopolymer concrete to reduce the disposal of these waste materials and make Australia greener.

ILCCC 2019 24-26 June, London GBR The construction industry has been under pressure to shift towards sustainability by manufacturing Portland cement in energy-saving ways and developing alternative low-carbon cement and concrete technology.

However, due to the gap between fundamental research and industrial use, as well as the lack of standards and a skilled workforce in this area, industrial applications are still scarce.

To address these challenges, the first international conference on Innovation in Low-Carbon Cement and Concrete technology (ILCCC) will be held on the 24 - 26th June 2019 in London, organised by the Advanced & Innovative Materials (AIM) Group. The conference provides the opportunity to exchange the latest global scientific and technical achievements on low-carbon cement and concrete technology, in order to promote wide industrial applications. In addition, there will be a formal banquet dinner on the second evening, aboard a paddle steamer boat ride along the Thames river.
