PROBLEM TO BE SOLVED: To easily perform highly reliably salt permeation tests on concrete, by bringing the whole front and rear surfaces of a concrete test piece into contact with a test solution, while the occurrence of wasters is being suppressed. SOLUTION: After a rubber material 5 is wound around the columnar concrete test piece 1, the material 5 is adhered in liquid-tight manner to the peripheral surface of the piece 1, by fastening the material 5 tight by winding a band 6 around the material 5. Then cylindrical containers 2A and 2B, into which the test solution is poured from the front and rear surfaces 1a and 1b sides of the piece 1 are installed, so that the opening-side edge sections of the containers 2A and 2B is joined in liquid-tight manner to the front and rear surfaces 1a and 1b of the piece 1. After installation, the test solution is poured into the containers 2A and 2B from their test solution inlets, so that the test solution is brought into contact with the whole front and rear surfaces 1a and 1b of the piece 1 and the permeating amount of a chloride ions is measured by applying a voltage across electrodes 4A and 4B. |
