<p>PROBLEM TO BE SOLVED: To provide a degradation diagnostic tool in which diagnosis of a degradation environment of a concrete structure can be performed by only that a constant quality mortar panel is adhered without breaking a concrete structure as coring.SOLUTION: A degradation diagnostic tool is characterized being a panel 1 of a mortar in which a cement in which a background is known, a silica rock based fine aggregate, and/or an alumina matter fine aggregate are used, a water/cement ratio is 30-70%, a fraction of the cement to the fine aggregate is in a range of 1 to 0.5-1 to 4 by a mass ratio, and a thickness is in a range of 3-20 mm, is characterized in that 0.05-2.0 pts.mass of a thickening material, and 0.05-2.0 pts.mass of an antifoamer are added based on 100 pts.mass of the cement in the mortar, and that being a fresh property and there is not breeding, is characterized in that an area of the mortar panel 1 is 5-100 cm, and is characterized in that a reaction rate of the cement is at least 80%.</p> |
