STRENGTH ESTIMATION METHOD OF SOIL CEMENT
To provide a strength estimation method of soil cement with which strength estimation is possible without securing curing period until the soil cement hardens.SOLUTION: A strength estimation method of soil cement includes a process to measure moisture content of the unconsolidated sample by drying an unconsolidated sample of soil cement formed by mixing cement milk and in situ soil, a process of pulverizing the dried unconsolidated sample and measuring the content of predetermined element in the unconsolidated sample using fluorescent X-ray analyzer, a process to calculate content of given element in unconsolidated sample using predetermined element content of the unconsolidated sample and predetermined element content of the in-situ soil, a process to calculate effective cement-water ratio of the unconsolidated sample using water content of the unconsolidated sample and cement content calculated from the content of predetermined element in the cement and a process of estimating compressive strength of the soil cement from the correlation data between the effective cement water ratio and the compressive strength.SELECTED DRAWING: Figure 4
