Therefore, the finishing agent had better use in case of high strength concrete, the wet curing had better carry out on concrete surface. However, it is not obvious that when wet curing is started after finishing of concrete surface. In this study, the effects of the difference in finishing methods and curing methods on the surface properties of concrete were examined by surface tensile test, air permeability test, water absorption test and scaling test. As a result, use of the finishing agent was effective to improve the surface properties in high strength concrete. However, use of the finishing agent was ineffective in normal strength concrete. When wet curing was carried out, high strength concrete was more effective than normal strength concrete. The surface properties of concrete could be improved when the wet curing was begun after it passed for several hours from finale set of the setting time test for concrete., 本研究では,コンクリート床版の表層品質の観点から,普通ポルトランドセメントおよび早強ポルトランドセメントを用いたレディーミクストコンクリートを使用し,コンクリート打込み後の仕上げ補助・養生剤の有無による仕上げ方法の違い,シートや湿潤マットを使用した養生方法および給水養生開始のタイミングの違いがコンクリートの表層品質に及ぼす影響を検討した.そして,表層強度を評価する表層引張試験,物質移動抵抗性を評価する表層透気試験および表面吸水試験,耐凍害性を評価するスケーリング試験を行い,適切な給水養生開始のタイミングを評価した.}, pages = {28--34}, title = {養生方法および給水養生のタイミングがコンクリートの表層品質に及ぼす影響}, year = {2021}, yomi = {サカモト, タイガ and サワモト, タケヒロ and モリハマ, カズマサ and シノザキ, トオル and ヒグチ, マサノリ and ダイ, アキヨシ} }
