• The two components of mortar, namely, the binding material and fine aggregates are sometimes referred to as the matrix and adulterant respectively. • The matrix binds the particles of the adulterant. The durability, quality and strength of mortar will mainly depend on the quantity and quality of the matrix. • Mortar is used to indicate a paste prepared by adding required quantity of water to a mixture of binding material (cement or lime) and fine aggregate (sand).
