CEMENT MILK SUBSTITUTION RATIO ESTIMATION METHOD AND SOIL CEMENT STRENGTH ESTIMATION METHOD
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
【課題】養生期間を確保せずに、セメントミルク置換率を推定する。【解決手段】セメントミルク置換率推定方法は、セメントミルクと現場発生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を乾燥させる工程と、乾燥した未固結試料を粉砕し、蛍光Ｘ線分析計を用いて、未固結試料の所定元素含有量を測定する工程と、未固結試料の所定元素含有量、現場発生土の所定元素含有量及び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、算出された前記質量比、現場発生土の含水比、密度、前記セメントの密度及び前記セメントミルクにおける水とセメントとの質量比から、前記ソイルセメントにおける前記セメントミルクの割合を算出する工程と、を備える。【選択図】図２
