CONCRETE SURFACE IMPREGNATION MATERIAL
To provide a concrete surface impregnation material which can be easily applied to a vertical surface or an upper surface because of its excellent anti-sagging property, has a large impregnation depth, is excellent in impregnation into concrete, has no problem in the appearance of a concrete surface after application and impregnation, shows high water repellency, and can improve durability.SOLUTION: A concrete surface impregnation material contains (a) an alkylalkoxysilane represented by formula (I) or a partially hydrolyzed condensate thereof, RaSi(OR')4-a...(I), (b) a fibrillated fluororesin, and (c) an organic solvent. In the formula (I), R is a 1-20C alkyl group, R 'is hydrogen or a 1-6C alkyl group, and a is 1 or 2.SELECTED DRAWING: None
【課題】タレ止め性に優れることから垂直面や上面に容易に塗布することができ、含浸深さが大きくコンクリートへの含浸性に優れ、塗布・含浸後のコンクリート表面の外観に問題がなく、高い撥水性を示し、耐久性を向上できる、コンクリート表面含浸材を提供すること。【解決手段】 (a) 式(I)で表されるアルキルアルコキシシラン又はその部分加水分解縮合物、 RaSi(OR’)4-a・・・(I)(式(I)中、Rは炭素数1~20のアルキル基、R’は水素又は炭素数1~6のアルキル基、aは1又は2である。)(b) フィブリル化フッ素樹脂、及び(c) 有機溶媒、を含有する、コンクリート表面含浸材。【選択図】なし
