Coal Ash Asia Handbook 2018

- Shuozhou City, Shanxi Province, China

The Asian Coal Ash Association proudly welcomes its members and following industry leaders to view our 2018 Coal Ash Asia Handbook. Coal Ash Asia is China’s premier coal ash handling, processing and utilization information exchange forum. China’s role in the coal ash industry is crucial, as it maintains the top spot for most coal consumed by a populous per year. We hosted our international event in Shuozhou City, China, and welcomed top researchers and commercial enterprises to share and explore leading research and technology. Our tracks included:

1. Coal Ash Processing and High Value Utilization

• Grinding, Classifying and Superfine grinding

• Cement, Concrete, Wall Materials and Geopolymer

• High Value Utilizations: Ceramics, Cenospheres, Fillers

• Sulphoaluminate cement CalciumSulphoAluminate

      2. FGD Gypsum Utilization

• Gypsum drying and Calcination

• Construction Applications: gypsum block, board, mortar

• Agricultural applications

• High Strength Gypsum, etc

     3. Coal Gangue and Coal Chemical Residue

• Processing and Utilization

     4. Metal Extraction

• Alumina and other metal extraction best practices and methods

Autoclaved Aerated Concrete: CCPs Growth in Asia Pacific

Between 2015 and 2021, the global autoclaved aerated concrete market is expected to increase by just under $2 billion USD.  AAC is increasing in industry wide use due to its light weight and versatility. The construction material consists of fly ash and gypsum, both biproducts of burning coal to make energy, and much less costly than their alternatives, sand and anhydrite.  The material also consists of lime, cement, and aluminum powder. Construction companies are increasing their use of this material as it is not only more cost efficient, but also provides wider durability to seismic fluctuation, intense heat, and pests. The material itself also saves the manufacturer or construction company in water and energy usage.  Autoclaved aerated concrete is widely used in Europe and North America.

AAC materials can either be used instead of or to repair common building materials. Application can be seen in most real estate areas including residential, industrial and commercial. However, the majority of the AAC market has been residential since its inception, and continuing throughout 2017 with a third of the overall market. The product types of autoclaved aerated concrete are distributed into tiles, panels, blocks, lintels and others.

The growing market is propelled by elements such as the increased importance of utilizing green building materials, the use of recycled materials themselves (fly ash, etc), and its superiority to commonly used materials for the same purpose.

Currently, limited adoption is due to high start up costs associated with AAC, and because manufacturing facilities are not yet commonplace, resourcing and logistics becomes problematic.

As adaptation grows however, and infrastructure is set in place, the forecast for AAC paneling is projected to grow almost 8% in the next 5 years.

Globally, Europe has lead in market consumption. However, the Asia Pacific region, including countries like China, Thailand, Malaysia, Singapore and Indonesia are expected to increase consumption by over 10%, also within the next 5 years.

Opportunities in the AAC market are real as there is strong interest in China, India and other densely populated regions who would benefit from disaster resistant structures made from coal combustion products (CCPs).

Presenters and Attendees at Coal Ash Asia 2017

-- Beijing

With CAA2017 just weeks away, we are proud to be hosting sizable international content and present our final speaker list at this year’s event. Our friends at the Slag Association of Asia will be hosting a concurrent event “Slag and Tailings Asia” in the same location at the Sheraton Grand Dongcheng Beijing Hotel.  Those who have registered for one will gain access to both events. All attendee will receive contact information for all 600 guests at this year's event and complimentary business and academic matching.

Sustainability Through CSA Cement

- Malaysia

Sustainability is simply the ability to meet the demands of today without negatively impacting the future. This goal is not easily met, especially in the construction industry. With demands for building materials on the rise in places like Malaysia and Vietnam, companies scramble to provide quality building materials such as concrete, cement, ceramic, etc, while still adhering to ever tightening restrictions on emission and waste disposal. Switching unfriendly environmental practices to a more efficient infrastructure of Building materials manufacturers providing suitable coal ash byproducts from local power station waste is not yet common practice. As legislative reform takes its time, researchers are attacking the problem of reusing industrial waste from all angles.

CSA (Calcium Sulfoaluminate) cement is another approach at reducing energy to produce environmentally friendlier cement.  Calcium Sulfoaluminate requires lower heating temperatures to produce. CSA is composed of a mixture of bauxite, limestone and gypsum and burning these at lower temperatures emits representatively lower amounts of carbon dioxide into the atmosphere. Also, the amount of limestone needed is much less. Limestone is said to be one of the key emitters of carbon dioxide in the sintering process. Using less materials and less energy is not only better for the environment, but more appealing to building materials manufacturers.

Dr. Tom Robl, Associate Director, Environmental & Coal Technologies at University of Kentucky’s Center for Applied Energy Research will be presenting the latest research and discussing CSA cement at the upcoming Coal Ash Asia. To join Tom at this year’s event please register by Clicking Here!
