FST Distinguished Talk – Foam Concrete for Energy Absorbing ApplicationsSpeaker: Prof. David A. Lange from University of Illinois Urbana-ChampaignHosted by: Prof. Wanhuan ZHOU

The Faculty of Science and Technology at the University of Macau hosted a distinguished lecture titled “Research on Foamed Concrete for Energy-Absorbing Applications,”on  January 26, 2026,  featuring Professor David A. Lange, Emeritus Professor from the University of Illinois Urbana-Champaign, as the keynote speaker. Drawing upon his profound expertise, Professor Lange offered an insightful analysis of foamed concrete’s vast potential as a next-generation lightweight construction material, particularly highlighting its exceptional promise in critical safety applications such as aircraft arresting systems at airport runway overrun zones. He meticulously explained how X-ray computed tomography enables precise characterization of the foam’s microstructure, and how this is integrated with advanced computational models to simulate its mechanical behavior under compression—thereby uncovering the complex response mechanisms under dynamic loading. Moreover, Professor Lange underscored the strategic incorporation of recycled fine-particle waste into the manufacturing process, which not only promotes efficient resource recycling but also paves the way for greener, more sustainable construction practices.

The seminar drew participation from 80 academics, faculty members, and students, fostering a vibrant atmosphere with lively discussions and active engagement. Throughout the lecture, cutting-edge research in cementitious composites was presented with remarkable clarity and rigor, offering invaluable inspiration and clear direction for the future innovation of smart, eco-friendly building materials.

澳門大學科技學院於2026年1月26日隆重舉辦一場題為「泡沫混凝土在能量吸收應用中的研究」的傑出講座，誠邀美國伊利諾伊大學厄巴納–香檳分校榮休教授David A. Lange擔綱主講。Lange教授以其深厚的學術造詣，深入剖析泡沫混凝土作為新一代輕質建材在能量吸收領域的廣闊前景，尤其在機場跑道安全溢出區等關鍵防護場景中展現出卓越潛力。他詳盡闡述如何運用X射線斷層掃描技術精準解析泡沫微觀結構，並結合先進計算模型模擬其在壓力作用下的力學行為，從而揭示材料於動態載荷下的複雜響應機制。此外，Lange教授特別強調將回收細顆粒廢棄物融入製程之中，不僅實現資源高效循環，更為綠色可持續建築開拓新路徑。

是次研討會吸引了80位專家學者及師生踴躍參與，現場氣氛熱烈，互動頻繁。整場演講內容前沿、邏輯縝密，充分彰顯水泥基複合材料領域的尖端研究成果，為未來智慧與環保建材的創新發展提供了寶貴靈感與方向。
