SELF-HEALING MORTAR AND SELF-HEALING CONCRETE
PROBLEM TO BE SOLVED: To provide a self-healing mortar and a self-healing concrete capable of spontaneously blocking generated cracks and reducing water leakage.SOLUTION: A self-healing mortar contains a binder, a fine aggregate, a chemical admixture and a milling mixing water. The fine aggregate contains soft blast furnace slag fine aggregate of 30 vol.% to 100 vol.%. Percentage of the milling mixing water to the binder is 30 mass% to 50 mass%. It is suitable to contain the binder of 500 kg/mto 1500 kg/min 1 mof the mortar, the milling mixing water of 150 kg/mto 500 kg/mand the fine aggregate of 300 kg/mto 1500 kg/m. The self-healing concrete contains the self-healing mortar and a coarse aggregate.SELECTED DRAWING: None
【課題】発生したひび割れを自発的に塞ぎ、漏水を減少させることが可能な自己治癒モルタル及び自己治癒コンクリートを提供すること。【解決手段】本発明の自己治癒モルタルは、結合材と、細骨材と、化学混和剤と、練り混ぜ水とを含む。前記細骨材は、軟質高炉スラグ細骨材を３０体積％以上１００体積％以下含む。前記結合材に対する前記練り混ぜ水の割合が３０質量％以上５０質量％以下である。前記モルタル１ｍ３中に、前記結合材を５００ｋｇ／ｍ３以上１５００ｋｇ／ｍ３以下含み、前記練り混ぜ水を１５０ｋｇ／ｍ３以上５００ｋｇ／ｍ３以下含み、前記細骨材を３００ｋｇ／ｍ３以上１５００ｋｇ／ｍ３以下含むことが好適である。本発明の自己治癒コンクリートは、前記の自己治癒モルタル及び粗骨材を含む。【選択図】なし
