Test results show chloride ions critical content in immersion conditions is always larger than that in cycle of dry and wet for the same concrete, that is, test conditions affects chloride ions critical content value. in the same conditions, water / binder ratio obviously affects chloride ions critical content, but the influence of fly ash or slag on chloride ions critical content is not obvious. it is obtained the equation that chloride ions critical content change with water / binder ratio through linear fitting experiment data
結果表明，同技術條件的混凝土試件，在全浸泡條件下的氯離子臨界濃度均要大於干濕循環條件下的，即臨界濃度大小受到試驗條件的影響；相同的試驗條件下，水膠比對氯離子臨界濃度大小有顯著地影響，而摻入適量的粉煤灰或礦渣粉對氯離子臨界濃度無明顯地影響。 -
