I would take a look at this http://m.dumondchemicals.com/pro-peel-away-1.html

It says environmentally safe and biodegradable paint stripping system for removing up to 30+ coats of paint in a single application from most surfaces, (i.e., wood, brick, concrete, stone, stucco, plaster, cast iron, steel, marble, and most fiberglasses).

The Festool RAS is definitely the right tool for that project. It will eat through paint on concrete very well.

If it’s a small amount the RAS or a Rotex will work, but you’ll burn through abrasives quickly.

At some point it makes sense to get a concrete surfacing grinder. This will be a lot faster and easier. If you go this route don’t plug it into a Festool vac. I believe they draw too much power.

If you want to continue with Rotex try 24 grit Saphir.

In the UK, I bought some stuff that was like a thick paste, you brush, or better still trowell it on, leave it to work it’s magic, then peel off,and hose down.

I used it to removed paint from concrete, mortar and decorative brickwork, and it worked very well, much better than I expected.
I will try and find a link.

Another vote for Peel Away. 

It's been a number of years since I purchased or used the product.  It comes in varying strengths, 1 and 7, with 7 being the more gentle.  I used Peel Away 1 on some wood trim and found it difficult to neutralize once done, which caused issues when re-painting.  Peel Away 7 proved to be a better product for interior work.  I've never tried it on masonry. 

When you run out of the paper that comes with the product, you can use freezer paper, with the coated side up - a cheaper alternative to buying more of the Peel Away branded paper.
