Cements

Cements are fine powders made primarily from limestone and clay that, when mixed with water, form a paste that hardens over time. This hardened material binds sand, gravel, and other materials together to create concrete, which is used in construction to build buildings, roads, and bridges. The chemical reactions between the cement and water, called hydration, give concrete its strength and durability. Cement is essential for creating a sturdy, stable foundation in various construction projects, providing the internal cohesion that holds the structure together securely.
