| Abstract: | Concrete test sample of three joint material dosage is placed near an acid river, air exposure is carried out, the character of test sample is measured, and a change situation is analyzed. By the observation and measurement,degradation of test sample was boiled to some extent and accepted. Considering the examination result, the deterioration depth and omission depth of concrete have a remarkable increase in connection with the age, and the amounts of change are 0.7 mm/yr, and 1.3 mm/yr, respectivdy. |
