And they can affect concrete surface because of bleeding water, dryness of surface water, and so on. However, correlation between variation of concrete surface and measurement value of semi-destructive testing has not been obvious. In this study, the effects of concrete surface properties on rebound number, rebound speed ratio, and scratch width were investigated. The main conclusions are as follows. (1)The rebound number of the top surface of the member was smaller than that of the side surface. And, the rebound speed ratio showed the same tendency as the rebound number. (2)The rebound number of concrete cured in water was smaller than that of concrete cured in air. And, the rebound speed ratio showed the same tendency as the rebound number. The scratch width of concrete cured in water was wider than that of concrete cured in air. (3)The rebound number and the rebound speed ratio of concrete at the age of 91 days were higher than those of concrete at the age of 28 days., 本研究では,コンクリートの測定面・養生・材齢の違いが,リバウンドハンマーによる反発度・新型シュミットハンマーによる反発速度比および引っかき試験器による引っかき傷幅の測定値に及ぼす影響について検討を行った.}, pages = {50--55}, title = {コンクリートの表面性状が各種微破壊試験の測定値に及ぼす影響}, year = {2012}, yomi = {ゴトウ, マサアキ and サワモト, タケヒロ and トビナイ, ケイシ and オオツカ, シュウゾウ} }
