Evaluation of Various Finishing Materials Contributing to Carbonation Suppressive of Concrete in Structures

Part2 Investigation Results of Literature (Coating Materials for Textured Finishes, Liquid-applied Compounds for Waterproofing Membrane Coating, Paint and Surface Penetrant)

Abstract

In this report, we investigated the literature concerning the carbonation suppressive effect of finishing materials. As a result, the following was confirmed. 1) The carbonation suppressive effect of the thin coating materials for textured finishes tended to be low. 2) In a state without deterioration of the coated finish, the thick coating materials for textured finishes had a high carbonation suppressive effect, because it was neutralization rate around 0.4. 3) Liquid-applied compounds for waterproofing membrane coating had an extremely high carbonation suppressive effect, because it was neutralization rate around 0 when the standard membrane thickness was more than 1mm. 4) Surface penetrant expects a carbonation suppressive effect according to the type of it.
