Durability of concrete/mortar made with recycled Port Augusta fly ash
Hallett Group Pty Ltd and University of South Australia exploring the challenges in the cement and concrete industry. This project leverages UniSA’s expertise in concrete research and Hallett Group’s leadership in the field, exemplifying a collaborative approach that bridges the gap between academia and industry.
Project Overview:
Durability of Concrete/Mortar with Recycled Fly Ash
This project explores the use of recycled fly ash in concrete/mortar and its effects on durability. The research aims to support sustainable construction practices in South Australia by improving the understanding of long-term durability.

Industry Perspective:
Industry supervisors Massimo Capasso (General Manager – Production Innovation and Sustainability) and Weiwei Duan (Researcher – Green Cement Applications) comment: “Partnering with UniSA drives the environmental and technological advancement of Hallett Group’s green supplementary cementitious materials (SCMs).”
University Perspective:
Prof Yan Zhuge, Dr. Tom Benn, and Dr. Reza Hassanli will be providing academic supervision to the candidates. “This collaboration addresses significant environmental and industrial challenges by re-using iron-rich slag, enhancing UniSA’s research in sustainable solutions and innovation in manufacturing practices.”
Student Perspective:
Tohid Yahyaee, PhD Candidate: “This is an exciting opportunity to contribute to sustainable construction practices through innovative research. I am thrilled to work alongside talented industry and academic professionals on research that promises new insights and meaningful impacts.”
Ziyu Sun, PhD Candidate: “This project offers a unique opportunity to address research gaps in slag-based SCMs, develop my problem-solving skills, and make a positive societal impact by reducing emissions and protecting the environment.”
Thanks to Patrick Allington for facilitating this project.
