Abstract
The carbonation law in ettringite crystal is studied in this paper, an d the following model is supposed, the unidimensional diffusion is the controlling step in the initial stage, the reaction accords with the fission model in the medium stage, and the controlling step is the fir st-order reaction in the later stage. The carbonation,kinetic equation s are derived from above model, and they fit well with empiric data.
