Zusammenfassung: | To estimate a dehydration rate of soil cement.SOLUTION: A soil cement dehydration rate estimation method comprises steps of: measuring the water content of an unconsolidated sample of soil cement formed by mixing cement milk and local soil; measuring the content of a predetermined element in the unconsolidated sample using a fluorescent X-ray analyzer; calculating a mass ratio of soil to cement in the soil cement using the content of the predetermined element in the unconsolidated sample, the content of the predetermined element in the local soil, and the content of the predetermined element in the cement used in the cement milk; calculating an effective cement water ratio of the unconsolidated sample using the water content ratio of the unconsolidated sample and the mass ratio; and calculating the dehydration rate of the soil cement from the calculated mass ratio, the water content ratio, the effective cement water ratio, the water content ratio of the local soil, and the water-cement ratio in the cement milk.SELECTED DRAWING: Figure 1
【課題】ソイルセメントの脱水率を推定する。【解決手段】ソイルセメント脱水率推定方法は、セメントミルクと現地土とを混合して形成されたソイルセメントの未固結試料の含水比を測定する工程と、蛍光X線分析計を用いて、前記未固結試料の所定元素含有量を測定する工程と、前記未固結試料の所定元素含有量、現地土の所定元素含有量及び前記セメントミルクに用いられるセメントの所定元素含有量を用いて、前記ソイルセメントにおける土とセメントとの質量比を算出する工程と、前記未固結試料の含水比と、前記質量比と、を用いて、前記未固結試料の有効セメント水比を算出する工程と、算出された前記質量比、前記含水比、前記有効セメント水比、現地土の含水比及び前記セメントミルクにおける水セメント比から、前記ソイルセメントの脱水率を算出する工程と、を備える。【選択図】図1 |
