Public PhD defence of Qinjian WANG on "Improving the Durability, Circularity, and Healing Capabilities of Sulfur Concrete"

Published on March 25, 2026 – Updated on March 25, 2026

Sulfur concrete is considered one of the most promising alternatives to conventional cement concrete because of its rapid strength development, excellent corrosion resistance, recyclability, and low carbon footprint.



However, its relatively poor long-term durability has significantly limited its broader application. In this study, hematite was first employed as a partial replacement for silica sand aggregate to improve the durability of sulfur concrete under high-temperature cycling conditions (20–110 °C). In addition, this study proposes for the first time the incorporation of microwave-responsive materials (graphite/carbon black) or electromagnetic induction-responsive fibers (steel wool/steel fibers), enabling remelting and thus, cracked sulfur concrete to heal and recover its structural strength.
