PROBLEM TO BE SOLVED: To provide a method enabling the quick elution of harmful matter from concrete, without crushing the concrete. SOLUTION: A concrete test piece 12 is immersed in a water tank 14 containing pure water, and an anode plate 22 and a cathode plate 24 are positioned on both sides thereof. A dc power supply 28 produces a potential difference between the plates 22 and 24 to make an electric field act on the concrete test piece 12. |
