Event Summary
NEXGen: Sustainable Solutions to harvest fly ash; and repair sewer networks.
This webinar invites two of our Next Generation to review two concrete sustainability projects from South Australia.
PRESENTERS:
Weiwei Duan
Hossein Ataabadi
PRESENTATION DETAILS:
The webinar will contain two sections:
Harvesting “Salt Water Sluiced” Coal Fly ash in South Australia. Weiwei Duan.
Synopsis: This presentation reviews research to harness fly ash at Port Augusta, South Australia. The fly ash that had previously been captured by salt water sluicing, is washed and dried to reduce salt content. Particle size distribution is also improved. The study underscores the importance of processing approaches for industrial byproducts to meet future SCM requirements and contribute to sustainable construction practices.
An Innovative Capsule for Self-healing Cementitious Materials Using Waste-derived Sludge. Hossein Ataabadi.
Synopsis: This presentation reviews research being conducted to heal concrete cracks by using sludge from drinking water treatment plants. The sludge is combined with calcium hydroxide to fill the cracks. The pozzolanic reaction of the sludge with the reactivity of calcium hydroxide in the presence of water forms calcium carbonate which produces an effective autonomous crack healing result. The combined sludge calcium hydroxide is encapsulated in 5-8 mm capsules that can be delivered and used to heal cracks on the inside of sewer pipes and sewer network systems.
The webinar will run from 2.00pm to approximately 3.00pm (AEDT). It is conducted online on the Zoom platform and delegates will be emailed login details and a password for this webinar prior to the event.

Presenters
Weiwei Duan is a researcher at Hallett Group and a PhD candidate in Civil Engineering at the University of South Australia. His current research focuses on developing sustainable cementitious materials as part of the Green Cement Project at Hallett Group. Weiwei has a strong interest in cementitious materials and alkaline-activated materials and the use of industrial by-products in green construction solutions. He has co-authored multiple papers in leading Q1 journals with contributions on durability properties, including improved acid resistance, mitigation of alkali-silica reaction, and the development of eco-friendly binder systems.
Hossein Sanaei Ataabadi is a Ph.D. student in Structural Engineering at the Department of Civil Engineering, University of South Australia (UniSA). Hossein researches Sustainable Cementitious Materials and advanced structural materials, especially novel sorts of concrete including Polymer concretes. He has been involved in tutoring and lecturing some structural and related courses.
