Ingredients such as Portland cement, an essential binding agent; hydrated lime, which improves workability; sand, a carefully screened inert aggregate; and water, when mixed, produce mortar.

It is the binding material used to fill the spaces between masonry units. It acts as a vital sealant, forming a barrier against water infiltration and wind penetration, protecting the inner structure.

Mortar is used to secure steel reinforcement, ties, and anchor bolts into walls.

Mortar compensates for any surface irregularities in the masonry units and ensures complete contact and even weight distribution, preventing potential weaknesses in the masonry.

The color of the mortar is an essential parameter in the appearance of masonry. For specific needs, organic pigments can be added to mortar for coloration. White mortar is created using white masonry cement or Portland cement, lime, and white sand.

Mortar curing is crucial for optimal strength development. Proper curing conditions, like moisture retention, enhance the long-term durability of the masonry construction.

Other than masonry construction, mortar is also used for plastering, grouting the voids in masonry to hold reinforcements, and creating a base layer for placing tiles.
