STRENGTH ESTIMATION METHOD AND STRENGTH ESTIMATION DEVICE OF SOIL CEMENT
To provide a strength estimation method and strength estimation device of a soil cement using a blast furnace cement.SOLUTION: The strength estimation method includes: a step S1 of determining an amount of oxygen required for setting a prescribed amount of blast furnace cement to an apparent neutral point in a prescribed time by performing a neutralization reaction between a sample of a blast furnace cement used for soil cement and an oxygen of a prescribed concentration; a step S2 of determining the content of blast furnace slag fine powder in the sample on the basis of the previously determined prescribed relation and the amount of the oxygen determined in the step S1; and a step S3 of determining the strength of the soil cement, on the basis of the previously determined prescribed relation, the content of the blast furnace slag fine powder determined in the step S2, and the mass ratio between the blast furnace cement and water in a cement milk used for the soil cement.SELECTED DRAWING: Figure 1
【課題】高炉セメントを使用したソイルセメントの強度推定方法および強度推定装置を提供する。【解決手段】ソイルセメントに用いる高炉セメントの試料と所定濃度の酸とを中和反応させることにより、所定量の高炉セメントを所定時間で見かけの中和点とするのに必要な酸の量を求めるステップＳ１と、あらかじめ求めた所定の関係と前記ステップＳ１で求めた酸の量から、試料中の高炉スラグ微粉末の含有量を求めるステップＳ２と、あらかじめ求めた所定の関係と、前記ステップＳ２で求めた高炉スラグ微粉末の含有量と、ソイルセメントに用いるセメントミルクにおける高炉セメントと水の質量比から、ソイルセメントの強度を求めるステップＳ３とを備えるようにする。【選択図】図１
