NTU-CEE Distinguished Seminar Series: Professor Poon Chi Sun
Organized By
CEE Seminar Committee
Host By
Professor Tan Kang Hai
Topic
Net-Zero Concrete, a Pathway for Sustainable Construction
About the Seminar
This presentation explores the forefront of low-carbon concrete development, focusing on integrated strategies to reduce its environmental footprint drastically. Key areas covered in the presentation will include the formulation and application of novel low-carbon cements (such as waste-derived cement and carbonizable cement) and the utilization of carbon-captured supplementary cementitious materials, where industrial by-products or novel materials treated with captured CO2 replace high-emission clinker. The advances in low-carbon ultra-high-performance concrete and low-carbon lightweight concrete mixes will also be introduced. The presentation will also highlight CO2 utilization technologies, including direct CO2 mixing, CO2 foaming and accelerated CO2 curing, which permanently mineralize CO2 within the concrete matrix, enhancing early strength while sequestering carbon.
This overview demonstrates that a synergistic approach combining advanced materials, carbon capture and utilization, and innovative processes offers a viable pathway to achieve high-performance, low-carbon concrete for a sustainable built environment.
