表層コンクリートの品質と中性化進行に関する解析的検討

抄録

This paper theoretically examines and proposes simple computational methods of the carbonation progress of concrete when the quality of surface layer and internal concrete aren't the same but cementitious materials have been combined at the surface layer of concrete. It is based on the model that carbon dioxide moves at steady rate of diffusion according to Fick's law; reacts instantaneously with calcium hydroxide (Ca(OH)₂) at the boundary of the carbonation area and the non-carbonation area; and the boundary moves inside sequentially. The carbonation progress is simulated using data from previous papers.
