Additional strength and resistance against the rain penetration and other such weathering agencies.
In stone or brick masonry, it fills up empty joints, a thin liquid mortar used for such purposes is termed as Grout.

It should be sufficiently plastic easily placed on the bed is construction in the form of thin, smooth and uniform layer.

It should be durable and strong in itself on drying and hardening at the same time. It should not react in anyway with construction units.
It should set and garden quickly construction could be done with speed.
It should not develop any cracks on drying and should be able to maintain their appearance for quite long period.
It should capable of developing the designed stresses.
It should be economical to make without compromising on any of the qualities.
