Mortar Vs Cement Types of Cement Types of Mortar

 · Mortar Vs. Cement. The difference between mortar and cement is that cement is the bonding agent while the mortar is a product composed of cement sand and lime.. Both substances have different purposes as the cement is activated with water and forms a connection with other elements to form a solid object while the mortar is useful to keep bricks or stones together and cannot be alone
