PROBLEM TO BE SOLVED: To provide an instrument for porous material quality evaluation capable of quickly, easily, and reliably performing nondestructive quality evaluation of a porous material such as concrete and mortar without restrictions of applicable locations.SOLUTION: A porous material quality evaluation instrument for use when water is applied onto a surface of an evaluation target region of a concrete by spraying water, grasping a water application status until the water starts flowing without being absorbed by the concrete, and determining a quality of the concrete on the basis of this application status, includes: a front plate 1 having a first opening formed therein; a first back plate 5 having a second opening 6 formed therein; and a first side plate 10 coupling the front plate 1 to the first back plate 5 in parallel with a gap given therebetween. |
