How to remove construction adhesive from concrete?
Removing glue from any surface is a thankless task.  You will not be able to return the floor to an as-built state.  You're going to have to cover it with something.

You're going to have to dissolve it and scrape it.  And it's going to be a heck of job.

Some expert google-fu has yielded Baby Oil as a potential solvent.  Other suggestions were mineral oil.

However, I think a better solution would be to get a floor sander with a grinding pad and sand it off.  Remember to wear a dust mask.
