Mortar is mixture of cement, sand, aggregate and water. It may be in different ratio.

In this type of mortar, the cement is used as binding material. Depending upon the strength required and importance of work, the proportion of cement to sand by volume varies from 1:2 to 1:6 or more. It should be noted that surkhi and cinder are not chemically inert substances and hence they cannot be used as adulterants with matrix as cement. Thus the sand only can be used to form cement mortar. The proportion of cement with respect to sand should be determined with due regard to the specified durability and working conditions. The cement mortar is used where a mortar of high strength and water-resisting properties is required such as underground constructions, water saturated soils, etc.

The properties of cement is only react with water to get harden. But other materials not react the same. So the answer is cement.

Cement is a binding material because it consists of sio2, fe2o3, cao, ai2o3, water.

Because cement has both cohesive and adhesive property.

Mortar is prepared from sand cement and water it is very hardness material in building construction. Cement is a binding material.

Cement is used because it act as a gum material during construction.

Mortar is mixer of cement sand aggregate and water.

The mixing between sand &cement.

Binding materials utilized in construction for making concretes and mortars, in bonding together individual elements of structural components, in waterproofing, and so on.

Binding materials are powdered substances that have the capacity when mixed (with water) to form a plastic mass that later hardens into a strong, rock-like solid.
