中文摘要：
用等温吸附法测定了混凝土在系列氯化钠（NaCl）溶液中的平衡氯离子（Cl^-）浓度,计算了矿渣混凝土对Cl^-的总结合能力、物理结合能力和化学结合能力,研究了矿渣掺量对混凝土Cl^-结合能力影响的规律.结果表明：在固定水胶比和胶凝材料用量的情况下,随矿渣掺量的增加,混凝土对Cl^-的总结合能力和化学结合能力的变化趋势是先升后降;混凝土对Cl^-的物理结合能力的影响不大.混凝土具有最大Cl^-结合能力时的矿渣掺量（质量分数）为40%.
英文摘要：
Chlorine ion（Cl^-） equilibrium concentrations of concrete exposed to sodium chloride （NaCl） solutions with different concentrations were determined by the isothermal adsorption method. For slag concrete, the total CV binding capacity, physical adsorption capacity and chemical binding capacity were calculated, and the influence of slag content on the Cl^- binding capacity of concrete was investigated. The results show that for slag concrete with constant water-to-binder ratio and binder content, as the slag content is increased, both the total Cl^- binding capacity and the chemical binding capacity of slag concrete increase at first and then decrease, while the Cl-physical adsorption capacity is not influenced much. When the slag content is 40%, the total CV binding capacity of concrete reaches the highest value.
