内容記述 |
Inspection of reinforced concrete is important to ensure durability, and visual test and hammering test are widely applied to the inspection. In this study, reliability on the result of the visual test for cold joint and sand streak and the hammering test for checking concrete strength distribution was investigated, and it was clarified that error among those test results obtained by more than 100 students is fairly small. Then method to estimate durability of reinforced concrete based on visual test results is proposed and general concepts for applying the hammering test to evaluation of concrete strength distribution is described. The following (1) and (2) are main conclusions. (1). Relation between visual test result for cold joint and diffusion coefficient of chloride ion in hardened concrete is very close, so that the durability of reinforced concrete structure can be predicted based on visual test results according to Japan Society of Civil Engineers standard specification. (2). Hammering test results accord with dynamic elastic modulus, thus the hammering test play a important role to evaluate the distribution of concrete strength. Defects in concrete are also inspected, but as soon as the defects are observed, the defects must be broken or repaired because this hammering test is small distractive test. |
