Fundamentals of Cementitious Materials: Hydration, Porosity, and Strength

Understanding how cement-based materials form and degrade is essential for designing durable, modern structures. This text-based course guides you through the fundamental science of cement hydration, microstructural development, and mechanical performance. You will transition from simply mixing concrete to understanding the complex chemical reactions and physical changes that occur at the microscopic level, allowing you to predict material behavior, control porosity, and optimize strength for various engineering applications. What you'll learn: - Understand the fundamental chemistry of cement phases and the stages of the hydration process. - Analyze how pore structures form and how porosity directly influences mechanical strength and durability. - Evaluate the relationship between water-to-cement ratios and the resulting microstructural properties. - Explore the role of modern supplementary cementitious materials, such as fly ash and slag, in reducing carbon footprint and improving performance. - Apply testing principles to assess compressive strength, permeability, and long-term durability in cementitious systems. The course begins with foundational definitions of cement phases and chemical terminology before moving into the kinetics of hydration. You will then progress to studying pore network development and the mechanical properties of the hardened paste through clear, step-by-step written explanations. This course is designed for civil engineering students, materials science enthusiasts, and entry-level construction professionals seeking a solid theoretical foundation in cement chemistry, with no advanced prior knowledge required.
