Abstract
A material for cement which comprises a calcium salt powder with an inositol phosphate and/or a salt thereof as adsorbed on the surface thereof, the powder having a specific surface area of 60-120 m2/g. A method of producing a material for cement comprises the step of mixing a calcium ion-containing solution adjusted to alkalinity with a phosphate ion-containing solution to produce a precipitate, the step of maturing the precipitate-containing system while maintaining the alkalinity to obtain a calcium salt powder, the step of recovering the calcium salt powder and drying the same, and the step of immersing the dried calcium salt powder in a solution containing an inositol phosphate and/or a salt thereof to cause the inositol phosphate and/or salt thereof to be adsorbed on the surface of the calcium salt powder.
