STRENGTH ESTIMATION METHOD OF CEMENT IMPROVED SOIL
To provide a strength estimation method of a cement improved soil which can confirm compression strength of a cement improved soil in simple steps with less sample.SOLUTION: A strength estimation method of a cement improved soil estimates a compression strength of a cement improved soil by an X-ray diffraction method. The method comprises: a step S06 of measuring diffraction peak strength and a diffraction angle (2θ) thereof by performing X-ray diffraction to a sample collected from the cement improved soil to be estimated; and a step S07 of obtaining the compression strength of the cement improved soil from the measured diffraction peak strength on the basis of a relationship, obtained in advance, between the compression strength of the cement improved soil and the diffraction peak strength at the diffraction angle (2θ). The obtained compression strength is estimated to be the compression strength of the cement improved soil to be estimated.SELECTED DRAWING: Figure 1
