Water Vapor Sorption in Cementitious Materials: Introduction

This lecture introduces the concept of water vapor sorption in cementitious materials, covering topics such as sorption and transport mechanisms, important terms like adsorption and absorption, equilibrium pressure, pore width effects on sorption, and classifications of sorption isotherms. The instructor explains the significance of hysteresis in sorption, different types of isotherms, and the most adapted sorption type for cementitious materials.
