FUNCTIONS OF MORTAR

Quality mortar should satisfy the following functions:

1. It forms a binding or cementing layer between two courses of masonry in the structure.
2. Because of this binding property, it provides strength and stability to the structure.
3. In brick or stone masonry, it forms a uniform layer by filling open joints and holes as a grout in a thin liquid form.
4. It makes the masonry structure a homogeneous mass of structure, which can withstand both dead and live loads and loads due to natural reasons.
5. When used for pointing purposes, it provides high rigidity and protects the structure.
6. Provides a uniform smooth surface when used as a plaster.
7. It also forms a good surface for taking finishing materials like white/colour washing or painting.
8. It holds the aggregates together in concrete to form a homogeneous solid mass.
