SELECTION METHOD OF SAMPLE PREPARATION METHOD, AND SAMPLE PREPARATION METHOD
To provide a selection method of sample preparation method capable of facilitating the determination of which method, tapping method or rammer method, should be used to prepare the sample according to the characteristics of the soil, and a sample preparation method.SOLUTION: The selection method of sample preparation is a selection method which of the tapping method or the rammer method should be selected as the sample preparation method. The method includes the steps of: supplying solidified soil which is a mixture of sample soil and cement-based solidifying material into a cylindrical body placed on a flow table; pulling up the cylindrical body in the vertical direction and removing the same to leave only the solidified soil on the flow table; measuring the flow value of the solidified soil using the flow test according to JIS R 5201: 2015 "Physical test method for cement"; and determining whether the flow value is greater than or equal to the specified value, whether or not. When the flow value is greater than or equal to the specified value, the tapping method is selected; and when the flow value is less than the specified value, the Rammer method is selected.SELECTED DRAWING: Figure 1
【課題】土質の特性に合わせてタッピング法及びランマー法のいずれの方法で供試体を作製すればよいのかの判断を容易にできる供試体作製方法の選定方法及び供試体作製方法を提供すること。【解決手段】供試体作製方法としてタッピング法又はランマー法のいずれかを選定する供試体作製方法の選定方法であって、試料土とセメント系固化材とが混合された固化処理土をフローテーブル上に載置された筒体に投入し、筒体を垂直方向に引き上げて取り去ることにより、固化処理土のみをフローテーブル上に残し、固化処理土のフロー値をＪＩＳ Ｒ ５２０１：２０１５「セメントの物理試験方法」に準じたフロー試験により測定し、フロー値が所定値以上であるか否かを判定し、フロー値が所定値以上である場合にタッピング法を選定し、フロー値が所定値未満である場合にランマー法を選定する。【選択図】図１
