摘要
根据 Fick第二定律建立混凝土表面涂刷 Ca(NO2 ) 2 水溶液时 NO- 2 在混凝土中扩散模型以保护混凝土中钢筋 ,并用实验验证该模型的合理性。同时依据 NO- 2 扩散模型预测 NO- 2
The theoretical model of nitrite ion diffusion in concrete presented based on the diffusion equation of Fick's second law when nitrites were coated to the concrete surface for protection of steel in concrete and the model was evaluated with laboratory data. Finally, the duration of the protective effect of nitrites had predicted based on the present model.
