Mortar is an intimate mixture of binding material, fine aggregate and water. When water is added to the
dry mixture of binding material and the inert material, binding material develops the property that binds
not only the inert material but also the surrounding stones and bricks. If the cement is the binding
material, then the mortar is known as cement mortar. Other mortars commonly used are lime mortar and

material sand and then the proportioning, mixing, curing, properties and uses of different mortars is
