PROBLEM TO BE SOLVED: To provide a method and device for evaluating quality of a porous material, which achieve an easy quality evaluation of concrete on site.SOLUTION: Liquids (L1, L2, L3 to Ln) are applied to a target place (11a) on a surface of a porous material (11) a plurality of times, and flow-down distances (X1, X2, X3 to Xn) from the target place (11a) to places which each of the liquids (L1, L2, L3 to Ln) applied the plurality of times reach after flowing down are measured, so that the quality of the porous material (11) is determined on the basis of the flow-down distances (X1, X2, X3 to Xn). |
