<p>PROBLEM TO BE SOLVED: To provide a determination method and a determination device for an admixture in cement, enabling a kind and a mixed amount of the admixture in the cement to be determined in a short period of time by using a small amount of the cement.SOLUTION: The determination method for an admixture in cement comprises: a first step S1 of obtaining a heat generation characteristic of each of a base cement paste and a known cement paste, and obtaining a correspondence relationship between a rate of change of the heat generation characteristic of the known cement paste relative to the heat generation characteristic of the base cement paste, and an amount of the admixture contained in the known cement; and a second step S2 of obtaining a heat generation characteristic of an unknown cement paste and obtaining a rate of change of the heat generation characteristic of the unknown cement paste relative to the heat generation characteristic obtained in the first step S1, of the base cement paste to determine at least one of a kind of the admixture contained in the unknown cement and the amount thereof on the basis of the obtained rate of change and the correspondence relationship.</p> |
