Title:
CEMENT MILK SUBSTITUTION RATIO ESTIMATION METHOD AND SOIL CEMENT STRENGTH ESTIMATION METHOD
Document Type and Number:
Japanese Patent JP2022184338
Kind Code:
A
Abstract:
To provide a cement milk substitution ratio estimation method allowing a cement milk substitution ratio to be estimated without securely setting a curing period.SOLUTION: A cement milk substitution ratio estimation method includes steps of: drying an unconsolidated sample of soil cement formed by mixing cement milk and soil at a site; measuring a content of a specific element in the unconsolidated sample using a fluorescent X-ray analyzer after the dried unconsolidated sample is crushed; calculating a mass ratio of soil and cement in the soil cement using the content of the specific element in the unconsolidated sample, a content of a specific element of the soil at the site, and a content of a specific element in cement used for the cement milk; and calculating a ratio of the cement milk of the soil cement from the calculated mass ratio, a water content ratio and density of the soil at the site, a density of the cement, and a mass ratio of water and cement of the cement milk.SELECTED DRAWING: Figure 2
