Microstructure and chloride ingress

This lecture covers the analysis of microstructure and chloride ingress in cementitious materials, including mechanisms, binding capacity, and transport properties. It discusses the porosity, hydration degree, and different types of binding, such as chemical and physical binding. The lecture also explores the concept of solid solutions in cementitious materials and their significance in understanding diffusion. Additionally, it delves into XRD and SEM-EDX analyses to study the formation of solid solutions and the binding of chloride in C-S-H. The lecture concludes by examining the transport properties, including resistivity and conductivity, and the impact of porosity on the microstructure.
