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%。

Chlorine ion(Cl-)equilibrium concentrations of concrete exposed to sodium chloride(NaCl)solutions with different con-centrations were determined by the isothermal adsorption method.For slag concrete,the total Cl-binding capacity,physical adsorp-tion 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 Cl-binding capacity of concrete reaches the highest value.
