Carbonation Mechanism of Concrete

Abstract

Many investigation and studies have made in the past regarding carbonation of concrete, but hardly any explanation has been made concerning the basic mechanism by which carbonation occurs. The present study explains the mechanism of carbonation based on the chemistry of pore solution which has been spotlighted re-cently as a promising means of elucidating the deterioration mechanism of concrete, along with which it is pointed out that the chemical factor governing the rate of carbonation is the pH of pore solution.
