To provide a novel geopolymer that can simultaneously secure high injection property and loading property for crack repair or cross section restoration and appropriate usable life and excellent strength development under normal temperature.SOLUTION: The geopolymer for concrete crack repair or cross section restoration is obtained by mixing an alkali solution containing lithium silicate and sodium hydroxide with an active filler containing pearlite powder and blast furnace slag powder. There is also provided the geopolymer mortar for concrete cross section restoration which is obtained by adding fine aggregate to this geopolymer.SELECTED DRAWING: None
【課題】ひび割れ補修又は断面修復用として高い注入性と充填性、適切な可使時間及び常温下の優れる強度発現性を共に確保することのできる新たなジオポリマーを提供する。【解決手段】ケイ酸リチウム及び水酸化ナトリウムを含むアルカリ溶液に、パーライト粉末及び高炉スラグ粉末を含む活性フィラーを混合してなる、コンクリートのひび割れ補修又は断面修復用ジオポリマー、及びこのジオポリマーに細骨材を添加してなる、コンクリートの断面修復用ジオポリマーモルタル。【選択図】なし
