【摘要】 研究了磨细矿渣净浆和砂浆对外渗氯离子的结合性能 ,结果表明 :掺加 70 %磨细矿渣可使净浆和砂浆结合氯离子能力、尤其是化学结合能力大幅度增加 .但加入硫酸根后 ,其结合能力下降 ,原因为化学结合能力显著下降 ,而不是物理吸附性能明显减弱 .碱性增大会显著降低化学结合性能 .外加剂则会减弱净浆与砂浆对氯离子的物理吸附性能 .更多还原

【Abstract】 The chloride binding capability of mortar and paste blended with 70% ground granulated blast furnace slag (GGBS) is greatly increased, especially the chemical binding capability. The binding capability is greatly weakened when blended with some sulphate. The reason is that the added sulphate weakens the chemical binding capability. Alkalinity also weakens the chloride binding capability. Admixture can influence the physical binding capability.更多还原
