I don't deal with concrete much, but I do know that a variation of 
shot-blasting, using small beads of frozen CO2 works wonders in other 
kinds of abrasive cleaning.  Much the same as standard shot blasting, 
albeit somewhat less abrasive, it has the advantage of thermal abrasion 
and the pellets evaporate, reducing clean up.

I can't say that it's applicable on concrete, but I'd be surprised if ti 
didn't have some application.
