PROBLEM TO BE SOLVED: To provide a method of simply and quickly acquiring compacting properties of the concrete even in the case of a large quantity of a ready mixed concrete.SOLUTION: A ready made concrete C thrown into a receiving jig 2 which has a through-hole 2c is let pass through the through-hole 2c and let flow down from the receiving jig 2, while a load W acting on the receiving jig 2 is measured by a load cell 3, and an index P showing the compacting property of this ready mixed concrete is measured, thereby previously acquiring a relationship between the load W and the index P. Then, a ready made concrete Cr to be an object of acquiring a compacting property is thrown into the receiving jig 2 so as to be let pass the though-hole 2c from the receiving jig 2, while a load Wr is measured, and the compacting property of the ready made concrete Cr is acquired based on a relationship between this measured load Wr and a relationship between the load W previously acquired by an experiment in advance and the index P.SELECTED DRAWING: Figure 1 【課題】多量の生コンクリートであっても、その充てん性を簡便かつ迅速に把握できるコンクリートの充てん性把握方法を提供する。【解決手段】貫通穴２ｃを有する受け治具２に投入した生コンクリートＣを、貫通穴２ｃを通過させて受け治具２から流下させつつ、受け治具２に作用する荷重Ｗを荷重計３で測定し、かつ、この生コンクリートＣの充てん性を示す指標Ｐを測定して、荷重Ｗと指標Ｐとの関係を事前実験によって予め把握しておき、充てん性を把握する対象となる生コンクリートＣｒを受け治具２に投入して貫通穴２ｃを通過させて受け治具２から流下させつつ荷重Ｗｒを測定し、この測定した荷重Ｗｒと、事前実験により予め把握している荷重Ｗと指標Ｐとの関係とに基づいて、生コンクリートＣｒの充てん性を把握する。【選択図】図１
