Japanese: consistency
consistency

…On the other hand, if a system of axioms were to give rise to contradictions, it would lose its reason for existence. Therefore, it goes without saying that a system of axioms must be free of contradictions, i.e., consistent. Furthermore, it is desirable that the axioms do not contain anything extra, that is, anything that can be derived from other axioms. …

From [Concrete]

…First, what is required of fresh concrete is that it has high fluidity and is easy to work with, that is, it is soft enough to easily penetrate every corner of the formwork and reinforcing bars, and that the materials do not separate. The degree of softness of concrete, which is mainly due to the amount of water, is called consistency, and this is generally expressed quantitatively by a slump test in which concrete is packed into a cone-shaped container in a certain way, and the dimension (measured in centimeters and called slump) of the top of the concrete when the cone is pulled out is measured. The degree of ease of pouring and the degree of resistance to separation of the materials are called workability, and although an appropriate test method has not been developed to determine this, it is decided to measure the consistency, which is closely related to workability, and to judge it based on the results. …

【コンクリート】より

…まず固まらないコンクリート(フレッシュコンクリート)に要求されるものは,そのコンクリートの流動性が大きく,施工が容易であること,すなわち型枠や鉄筋のすみずみまで容易に行き渡る軟らかさをもつことと,材料の分離が起こらないことである。主として水量の多少によるコンクリートの軟らかさの程度を示すのはコンシステンシーconsistencyと呼ばれるもので,これは一般に,コーン状の容器に一定の方法でコンクリートを詰め,コーンを引き抜いたときにコンクリートの上部が下がった寸法(cmの単位で示しスランプと呼ぶ)を測定するスランプ試験により定量的に表される。打込みやすさの程度および材料の分離に抵抗する程度を示すものはワーカビリチーworkabilityと呼ばれ,これを判定する適当な試験法は開発されていないが,ワーカビリチーと密接な関係にあるコンシステンシーを測定して,その結果に基づいて判定することにしている。…
