KAWAKAMI HIROKATSU

PROBLEM TO BE SOLVED: To provide: functional hydraulic inorganic particles capable of easily providing a hydraulic composition excellent both in fluidity and clay resistance; and hydraulic particles containing the same.SOLUTION: There are provided functional hydraulic inorganic particles which contain hydraulic inorganic particles and satisfy the following conditions (I) and (II): (I) for a mortar composition comprising 225 pts.mass of water and 1350 pts.mass of standard sands based on 450 pts.mass of functional hydraulic inorganic particles, a ratio (F0/F2) between a 15-tap flow value (F0) determined by JIS R5201 and a 15-tap flow value (F1) of a mortar composition prepared in the same manner after heating the functional hydraulic inorganic particles at 550°C is 1.1 or more and (II) a ratio (F0/F2) between a 15-tap flow value (F0) under the above condition and a 15-tap flow value (F1) determined in the same manner as the 15-tap flow value (F0) except that 0.2 pts.mass of clay is contained based on 100 pts.mass of standard sands is 1.2 or less.SELECTED DRAWING: None
