To provide a method for treating a concrete hardened body in a reinforced concrete structure or a pre-stressed concrete structure, by which the denseness and durability of the concrete hardened body are improved.
The method comprises impregnating cationized polymer particles into pores in the surface part and/or inside of the concrete hardened body. Or, the cationized polymer particles are filled into the pores by supplying an electric current between outer electrodes and/or between the outer electrodes and internal electrodes using the electrodes provided at the surface parts and/or places near the surface of the concrete hardened body as the outer electrodes and using steel materials provided at the inside of the concrete hardened body as the internal electrodes.
