Mortar

In mortar, the binding material is the cement.

Cement acts as a hydraulic binder. When mixed with water, it undergoes a chemical reaction called hydration, hardening and adhering to other materials to form a strong, stone-like material. This binds the aggregates (sand) together, creating the mortar's cohesive and adhesive properties.

Common types of cement used in mortar include:

• Portland Cement: A widely used cement that provides high strength and durability.
• Lime: Offers good workability and water retention, often used in older buildings.
• Masonry Cement: A blend of Portland cement and other materials designed specifically for masonry work.
