advantage of using dry process of cement production

Dry-casting requires an expensive dry-casting machine and is typically used for mass production of products like concrete pipe or manholes and also in concrete block production. The big advantage of dry-casting is that you only need one set of forms to mass produce a specific part, since the form can be stripped immediately.
