PROBLEM TO BE SOLVED: To provide a quick hardening property between a setting start time and a setting end time of a one-powder type which is not a two-component mixed type using a hydraulic component composed of alumina cement, Portland cement and gypsum. An object of the present invention is to provide a hydraulic composition having an appropriate pot life. Further, a hydraulic composition for grouts including alumina cement, Portland cement, gypsum and lime system, which is non-shrinkable, has no volume change during curing, and has excellent short-time hardening between setting start time and setting end time. For the purpose of provision. A hydraulic composition comprising a hydraulic component composed of alumina cement, Portland cement, and gypsum, and a setting modifier. A hydraulic composition characterized in that the setting modifier comprises citrate and bicarbonate. [Selection figure] None |
