Abstract

In this paper, a mathematical model of carbonation process in porous concrete materials is proposed. Based on physio-chemical mechanisms, the whole process can be viewed as the multi-component flow coupled the carbon dioxide-moisture-calcium ion transport. The rate of calcium hydroxide dissolution and mass equations are modified to get better descriptions on the physical conservation. An uncoupled finite volume method is proposed to solve the nonlinear parabolic system. Numerical simulations under the normal carbonation condition and the accelerated carbonation condition are presented and analyzed, respectively.
