Sustainable Cementitious Materials

This lecture introduces the concept of engineered calcium silicate hydrates for sustainable cement and concrete applications, emphasizing the importance of transport in cementitious materials. It discusses the sustainability aspects related to economic, societal, and environmental factors, highlighting the need for monitoring, surface repair, partial replacement, and environmental remediation. The lecture also explores the compromise between cement chemistry and sustainability, aiming to minimize CO₂ emissions. Additionally, it delves into the microstructure of cement paste and the use of numerical methods such as molecular dynamics and finite element simulations to study transport phenomena in cementitious materials.
