摘要
In accordance with the invention, hydration-accelerating seeds composed of CSH phases or AFt/AFM phases or hemicarbonate or monocarbonate phases, or of a mixture of two or more of these phases, are used as an admixture for cement and/or concrete, the hydration-accelerating seeds having been obtained as follows:;a. using hot meal and/or bypass dust from a cement production operation as starting material,b. producing a suspension by mixing the starting material with an aqueous solution, until a solid consisting of hydration-accelerating seeds is formed, andc. removing the solid consisting of hydration-accelerating seeds from the aqueous solution.
