The past 15 years have witnessed a surge of atomistic simulation study of cementitious materials. To provide a platform for young researchers to learn modelling methodologies, and to communicate the state-of-the-art research results with each other, the International Conference of Atomistic Simulation of Cementitious Materials (ICASCM) steering committee is formed among researchers from several continents, with the first workshop planned to be host by National University of Singapore in July 22-24, 2024. This three-day event will cover a one-day hands-on training of modelling methods/tools by world-renowned researchers, and two days of extensive academic presentations. It will be an exciting tapestry of academic discourse, and an unforgettable experience of the beautiful tropic city-state of Singapore.
