What are the technical differences between traditional mortar and commercial mortar?

In traditional mortar, only the quality of cement is usually controlled, and other main components, such as sand, are basically the same as aggregate in concrete, only the fineness modulus and mud content are controlled, and chlorine content is also controlled in some areas.

Commercial mortar has the advantages of stable strength, good workability, high bonding strength, good impermeability, no crust, no explosion, centralized production, and no lime and air-entraining components.
