Every single update from the Australian Society for Concrete Pavements.

Coal Ash is so often misrepresented in the media, academics like Dr. Lisa Bradley are attempting to combat this issue.

Plently of exciting things coming from the Australian Society for Concrete Pavements!

 A number of Australian Standards relevant to the Sampling & Testing of Aggregates have been published recently. The purpose of the Standard is to provide general information on the requirements of standard pieces of equipment used throughout the AS 1141 series for the testing of aggregate and rock for engineering purposes.

In June 2019, the Sydney City Council along with University of NSW and Wagners Concrete worked together to lay 15 metres of Geopolymer Concrete in a busy street of Sydney. The project was part of 7 years of research together with UNSW and the Cooperative Research Centre for Low Carbon Living, which saw the concrete laid to undergo 5 years of testing against regular concrete laid as a control. 

The beneficial use of coal combustion products (CCPs) during 2018 resulted in 5.936 million tonnes or 47% being beneficially used, resulting in the conservation of; energy; finite natural resources, the reduction of carbon emissions through the recovery of CCPs being mineral by-product resources.

Following almost two years of consensus building discussions, the definition of what constitutes Class C and Class F fly ashes is now officially changed in the United States.  The American Coal Ash Association during their recent Winter meeting reported the likelyhood of changes to come.

AGL DECISION TO SUSPEND SUPPLY OF COAL COMBUSTION PRODUCTS 

The Ash Development Association of Australia (ADAA) representing Australian coal-fired power stations and marketers[1] of power station coal combustion products (CCPs), supports the decision by AGL’s Bayswater Power Station[2]  to suspend CCPs distribution until a full investigation is conducted into claims about elevated levels of trace metals. 

American Coal Ash Association has commenced celebrating the organization’s 50th anniversary!

Attendees at the recnt ACAA Fall Meeting in New Orleans enjoyed presentations reviewing the association’s history during the Women’s Leadership Forum and a commemorative group luncheon. Now that history can also be enjoyed in a five-minute video available on-line.

Multiple Standards Australia Drafts are open for comment, closing on 31 August 2018.  

Howard Recycling Services has the contract with Sunset Power International for the Sale of Bottom Ash, Cenospheres and Ash Dam Rejuvenation at Mannering Park Ash Dam. The company was established on site at this location in November 2012. 

Sphere One’s goal is to always provide the highest quality products and services to our customers by establishing and reviewing quality objectives.

The ASTM’s committee(s) for cement, SCM's and concrete currently have a host of issues open for the ballot. Our colleagues at the American Coal Ash Association’s have shared some keys issues their Technical Committee have been evaluating.  the Ash Development Association of Australia appreciated greatly the ACAA sharing these international developments so as to keep us abreast of international developments.

Being the largest supplier of construction materials to Australia, Boral have entered into a binding agreement to acquire headwaters Inc. for US$24.25 per share in cash, representing an aggregate enterprise value of US$2.6 billion.

​Latrobe Magnesium (ADAA Member) is hoping the coming closure of the Hazelwood power station will help spur a $12 million Victorian government grant that will let it ­finally start building a $40m pilot magnesium plant that would process Hazelwood’s fly ash waste. If successful, Latrobe Magnesium (LM) is planning a $325m plant that will likely employ 300 people from the region.

Available on Apple iBooks, Google Play Store and Amazon's Kindle to suit your every technologocial whim, the ADAA has developed this FactBook to appeal to not only CCP experts, but to everyone. The incisive 35 page summary is informative, and surprisingly comprehensive and knowledgeable, encapsulating a variety of topics.

Coal combustion residuals are often viewed as a troublesome burden—a waste product that coal-fired power plants struggle to deal with. Much has been written about disposal management strategies, and a lot of money is spent annually on landfills and monitoring. But in many cases, disposal is not the best option; beneficial use of the material could save money and reduce liability.

This article provides an interesting perspective on We Energies journey towards 100% benefical reuse of all coal combustion products from its faciliies, along with some novel developements and applications.

“Fly ash is not waste, it is a valuable resource.” These findings “promise to lift fly ash perceptions in the world” - Kunigal Shivakumar (director of Composite Materials Research Centre).

NSW transport and road funding highlights in 2016-17 includes, $2.9 billion allocated to WestConnex; $2.1 billion on upgrades to key regional highways; and $2.7 billion to deliver Sydney Metro (including $1.3 billion for Sydney Metro Northwest and $1.4 billion for Sydney Metro City and Southwest).

Queensland based company Coretrack Ltd has developed a new ceramic proppant made predominantly from fly ash, which are lightweight and inexpensive compared to its predecessors. The innovative proppant allows for deeper 'fracking' and can withstand higher pressures than traditional ceramic proppants.

A 2nd Edition of Procurement of Construction Products – A guide to achieving compliance was released in November 2015.  The Guide now recognises 34 industry led product accreditation schemes and guidance information across a range of building product categories including reinforcing and structural steel, cementitious materials for concrete, wood products, glazing products, electrical products, fire safety services, plumbing products, insulation products, coating products and building products. The Guide is an important and valuable contribution to the efficiency and reliability of the building and construction industry. This Guide has been jointly developed by 30 key construction industry stakeholders and supported by many others.
