How do you get rid of gasoline smell that spilled on concrete floor?

Concrete is porous! It Will go away by its self!

I work in the oil industry, and getting rid of smells, stains etc.. is a routine for me. The product I use to clean, remove smells from oil based products, gasoline, is called "Citrol" you can do a google search to find a supplier.

I purchase it from a local vendor called Howard Supply Co., they are located in many states, so perhaps one near you.

It comes in a aerosol, so it's easy to use, and store. If the job is bigger, it also comes in 5 gal. cans, which I use to clean tankers. I believe it is Bio safe as well, if that is a concern. Leaves a pleasant odor when finished.

I use this in the bed of my truck to remove oil stains, odors along with a brush to work it into the pores of the liner.
