This test method makes use of discolored boundary between AgCl and Ag₂O by spraying AgNO₃ solution. However, this method has some problems. In this study, some problems of this test method were resolved. The main conclusions are as follows. (1) The movement of discolored boundary ends passage of an hour after spraying AgNO₃ solution. (2) The content of total chloride ions at the discolored boundary is about from 2kg/m³ to 4kg/m³. (3) Spraying NaOH solution before spraying AgNO₃ solution is effective when the specimen is carbonated., 本研究では,明確になっていない硝酸銀溶液噴霧後の経過時間とともに生じる変色境界の移動,変色境界における全塩化物イオン量,中性化の対応として水酸化ナトリウム溶液噴霧および紫外線照射について検討した.}, pages = {9--17}, title = {硝酸銀溶液噴霧による硬化コンクリートの塩化物イオン浸透深さ試験方法に関する研究}, year = {2018}, yomi = {トベ, ココロ and サワモト, タケヒロ and モリハマ, カズマサ and アオキ, ユウスケ and カワマタ, コウジ} }
