Demineralised Water on Concrete





I want to know the chemical behaviour of demineralised water on concrete or epoxy resin; is it harmful for concrete in any manner?

Quote from Paper by Ray Sams, presented at "Surfex", held at G Mex centre, Manchester, 22nd June 2004. "Pure water will attack concrete leaching out the free lime, but this is a relatively slow process. If the water contains high levels of dissolved CO2 the attack can be severe and rapid".
My understanding is that wet CO2 causes carbonation of concrete, which leads to attack of rebar (see www.concrete-experts.com/pages/carb.htm).
