Cement gains strength with hydration. But despite its versatility and wide-spread use, all mortar is not the same. Also historic buildings are frequently constructed with relatively soft brick and many types of stone, and minor movement in such buildings is quite common due to the nature of the foundations. It is soft and pliant when it is being applied, then it sets into a hard concrete-like substance. 04. As a result, it has unique characteristics such as bonding properties, flexibility, and compressive strength. Lime used as a binding material. Lime is used instead of cement material. Reinforced brickwork: Cement mortar proportion 1:3: 10. Mortar can be used for a number of purposes such as plastering over bricks or other forms of masonry, for flooring etc., and with the addition of coarse aggregate, it can also be used to make concrete.
