While discussing my thesis title with my thesis advisor the following came up
Cement technology: Characterization**,** and applications in bridges and dams
I am concerned about a comma and I am not able to find the relevant rules to decide if the comma is correct or not. The reasoning seems to be that it could stand by itself 'Cement technology: Characterization' and the second part is a separate thing that also contains an 'and' and therefore has to be separated by a comma.
I am not a native speaker and for some reason the comma looks strange to me, can you dispel my doubts?
