| description | PROBLEM TO BE SOLVED: To provide a method capable of estimating compressive strength at a predetermined material age of soil-cement in accordance with a construction condition of a soil-cement development site.SOLUTION: A construction condition that is defined by physical properties of soil particles included in soil-cement, a mix proportion of cement milk included in the soil-cement and components of the cement milk included in the soil-cement is set. A relationship between a cement-water ratio C/Wscu of the soil-cement in the construction condition and compressive strength qu28 of soil-cement at predetermined material age is calculated. Based on measured density γscu of the soil-cement, the cement-water ratio C/Wscu of the soil-cement is calculated. By substituting the calculated cement-water ratio C/Wscu(=Ya) into the relationship, the compressive strength qu28 (=Za) of the soil-cement at the predetermined material age is estimated.
【課題】ソイルセメント造成現場の施工条件に応じた、ソイルセメントの所定材令の圧縮強度を推定することができる方法を提供する。【解決手段】ソイルセメントに含まれる土粒子の物理的性質、当該ソイルセメントに含まれるセメントミルクの配合割合及び当該ソイルセメントに含まれるセメントミルクの構成材料によって規定される施工条件を設定し、当該施工条件下でのソイルセメントのセメント水比Ｃ／Ｗscu と所定材令のソイルセメントの圧縮強度 qu28 との関係式を算出し、計測したソイルセメントの密度γscu から当該ソイルセメントのセメント水比Ｃ／Ｗscu を算出し、この算出したセメント水比Ｃ／Ｗscu（＝Ｙａ）を前記関係式に代入して、所定材令のソイルセメントの圧縮強度 qu28 (＝Ｚａ）を推定する。【選択図】図２ |
