Professor Yoon-Ho Cho earned his Ph.D. in Transportation Engineering from the University of Texas at Austin, USA, and possesses a comprehensive international academic background. He previously conducted research at the Center for Transportation Research (CTR) at the University of Texas and served as a senior researcher at the Korea Institute of Civil Engineering and Building Technology (KICT). Since 1998, he has been a faculty member in the Department of Civil and Environmental Engineering at Chung-Ang University, Korea, where he is currently a Professor. He has also served as Dean of the College of Engineering and Director of the Engineering Education Innovation Center. In terms of academic leadership, Professor Cho is a co-founder of the BESETO (Beijing-Seoul-Tokyo) International Conference on Concrete, promoting high-level academic exchanges in concrete and pavement engineering in East Asia. He has served as Vice President of the Korean Society of Road Engineers, President of the Korean Block Association, and Organizing Committee Chair of the International Conference on Concrete Block Paving (ICCBP). At the government and industry level, Professor Cho has long served as a member of the Infrastructure Management Committee under the Prime Minister's Office of Korea. He has also participated as a core expert in overseas infrastructure projects in countries including Honduras, Sri Lanka, Indonesia, the Philippines, Cambodia, and Laos, providing technical consulting and capacity building.

This lecture presents a hydration model for Portland Limestone Cement (PLC) that explicitly accounts for the nucleation effect of limestone particles. Fine limestone provides additional surfaces for C-S-H precipitation, accelerating early-age hydration, a physical effect often missing in traditional models. The talk covers the mechanism, model development, key parameters (e.g., limestone surface area), and validation against experimental data. Results show that including the nucleation effect significantly improves prediction accuracy for early hydration kinetics, offering a useful tool for designing low-carbon PLC mixtures.
