2. Cement

Concrete is a widely used construction material whose properties are significantly influenced by its ingredients: cement, aggregates, water, and optional admixtures. Each ingredient plays an essential role in determining the performance of concrete, including its strength, durability, and workability. A thorough understanding of these ingredients and their respective properties is crucial for civil engineers to design high-quality concrete that meets specific application requirements.
