Abstract
The relationship between the intrinsic permeability and the Carbonation of concrete is examined. It is shown that the Figg air index test, which is portable, cheap and simple to operate, can be used to predict directly the potential resistance of concrete to carbonation. The water/cement ratio and degree of moist curing are the main factors influencing the quality of concrete in terms of its carbonation resistance.Keywords
