中文摘要: 通过检测不同条件下Li⁺离子在混凝土中的浓度变化和滞留量,考察了再碱化过程中物料的传递方式及其在该过程中的作用.结果表明:在电场作用下,锂离子通过电渗和电迁移由溶液向混凝土迁移;再碱化过程前期主要靠扩散实现,后期则主要由电渗和电迁移来完成.

中文关键词: 再碱化物料传递扩散电渗透电迁移

Abstract:In this paper,the change of Li + ion concentration in concrete and the residual in the concrete are measured under different conditions,the way of the material transfer and their affects in the process of realkalization are investigated. The results indicate that electro-osmosis and electromigration occur in electric field; the realkalization process mainly depends on the diffusion in the earlier stage while it mainly depends on the electro-osmosis and electro-migration in the later stage.

keywords: realkalization material transfer diffusion electro-osmosis electro-migration
