摘要

The paper aims to investigate the effects of fly ash (FA), slag (SL) and silica fume (SF) on the electrochemical chloride removal treatment with simultaneous migration of silicate ion, which was to - 2- alienate the Cl from the reinforcement and inject SiO3 into the mortar to interact with Ca(OH)2, respectively. The mortars (20% and 30% FA, 30% and 50% SL, 5 % and 10% SF) contaminated by 2.0 wt.% chloride were prepared. The chloride extraction efficiency and corrosion properties of steel reinforcement in sodium chloride solution after the electrochemical treatment were measured to evaluate the effects. Results show that this electrochemical treatment is effective in extracting chloride from the mortar with various admixtures and prolong the initial time of corrosion for the steel in mortar with various admixtures. With the increase of FA content in mortar, the extracted chloride efficiency and the initial time of corrosion for rebar in mortar were increased. In contrast, with the increase of SL or SF content in mortar, the extracted chloride efficiency and the initial time of corrosion for rebar were decreased.
