作者通过实验研究了硅酸盐水泥、高炉矿渣和火山灰的不同组合砂浆试样的氯离子结合能力。在实验中，通过孔液萃取法、氯离子滴定法、基于XRD法的Friedel盐定量分析、压汞孔隙测定法，分别测定了氯离子、孔壁上吸附的氯化物、固相氯化物（Friedel盐）。结果清楚地表明，弗里德尔盐的含量在很大程度上取决于所用粘合剂的类型，而吸附的氯化物则由微孔结构和水合产物的特性控制。
The authors experimentally studied the chloride binding capacity of mortar specimens made with various combinations of Portland cement, blast furnace slag, and pozzolans. In the experiment, a pore liquid extraction method, chloride titration test, a quantitative analysis of Friedel's salt based on the XRD method, and a mercury intrusion porosimetry test were conducted in order to measure chloride ions, adsorbed chlorides on the pore wall, and solid-phase chlorides (Friedel's salt), separately. It was clearly shown that the amount of Friedel's salt strongly depends on the type of binder used, whereas adsorbed chlorides is controlled by the micropore structure and the characteristics of the hydrated products.
