METHOD OF MANUFACTURING SOLIDIFIED SOIL
To manufacture a low-cost solidified soil having uniaxial compressive strength of 10 mega-newtons per square meter or more and having fluidity required at the time of manufacture.SOLUTION: A manufacturer measures a water content ratio of a raw material soil whose water content has not been adjusted, and sets this to an initial value to prepare a soil material having a known water content, and adds a solidifying material (or solidifying material and water) to the prepared soil material so that a water/solidifying material weight ratio after addition becomes a specified value, and stirs with a batch stirrer, and determines whether a fluidity of the manufactured solidified soil satisfies a condition, and further adds the solidifying material and water and stirs so that the water/solidified material weight ratio after addition and stirring maintains a specified value, when it is determined that the fluidity of the solidified soil does not satisfy the condition.SELECTED DRAWING: Figure 1
【課題】１０メガニュートン毎平方メートル以上の一軸圧縮強度を有しながら製造時に求められる流動性を有する固化処理土を安価に製造する。【解決手段】製造者は、水分未調整の原料土の含水比を測定し、これを初期値に設定することにより、含水比が既知の土質材料として準備する。製造者は、準備した土質材料に対して固化材（又は固化材及び水）を、添加後の水／固化材重量比が規定値になるように添加し、回分式の撹拌機によって撹拌する。製造者は、製造した固化処理土の流動性が条件を満たすか否かを判定する。固化処理土の流動性が条件を満たさないと判定した場合、製造者は、添加・撹拌後の水／固化材重量比が規定値を維持するように固化材及び水をさらに添加して、撹拌する。【選択図】図１
