SURFACE COATING OF CONCRETE MATERIALS BY DEPOSITION PROCESS.

A deposition process for coating concrete surface was presented in this study. This can be accomplished by feeding a weak direct current between the steel in a concrete and an electrode located in the external solution. The test was conducted using reinforced concrete prism specimens of 10 × 10 × 40 cm. Cracked specimens were immersed in an electrolyte magnesium acetate solution, and were applied with a constant current for 14 days. The results indicate that deposit materials are capable of coating the concrete surface and that this technique is effective for the improvement of the impermeability of concrete materials.
