When a European standard was compared with the claims postulated of a domestic standard, it was confirmed that direct comparisons of the evaluation results were difficult because a common evaluation item is a little and the test condition is also greatly different. The evaluation of performance of hydrophobic impregnation according to both domestic and international standard was conducted. Afterwards, the measured value and these grading were compared. As the result, the performance of watertightness and prevention of chloride penetration were greatly improved respectively, but it was not effective against inhibition of carbonation. In addition, further performance gain was hardly admitted when excessively coating it exceeding an appropriate amount.
