Mortar is a mixture of cement, water, and sand (and sometimes lime), used as a binding agent for bricks, stones, and other masonry materials.
Mortar has been used for thousands of years in construction, evolving from natural materials to today’s cement-based formulations. Its role is to bind and seal masonry, offering flexibility and workability essential for vertical and horizontal joints in walls and structures.
| Feature | Cement | Concrete | Mortar |
|---|---|---|---|
| Definition | A fine powder (binding agent) | A mixture of cement, sand, water, and aggregate | A mixture of cement, sand, water, and sometimes lime |
| Purpose | Used as a component in concrete and mortar | Builds structural elements like slabs and foundations | Binds bricks, stones, and blocks in masonry work |
| Strength | N/A (not used alone) | Strongest, load-bearing | Weaker, flexible, and adhesive |
| Texture | Powdery | Contains coarse aggregates (gravel) | Smooth, fine, no coarse aggregate |
| Usage | Ingredient in mixes | Structural (e.g., patios, walls) | Binding agent in walls, pavin |
The color and finish of mortar can dramatically influence the final look of masonry work. By adjusting the sand color, cement type, and additives, masons can create mortar that matches or contrasts with the masonry units.
