COATING MATERIAL FOR CONCRETE, AND PAINT FOR CONCRETE
PROBLEM TO BE SOLVED: To provide a coating material for concrete that can be easily coated even by a person other than a skilled construction operator.SOLUTION: There is provided a coating material for concrete in which a cement; a polymer for cement admixture; a water-soluble cellulose ether; and an antifoamer are mixed. The coating material for concrete comprises 5-15 parts by mass of the polymer for cement admixture, in terms of polymer solid content relative to 100 parts by mass of the cement, and 0.3-0.5 part by mass of the water-soluble cellulose ether. The concrete composition is added with 0.1-0.5 part by mass of the antifoamer. Further provided is a paint for concrete in which such coating material for concrete is mixed with 60-90 mass% of water based on a water/powder ratio relative to the coating material for concrete, and is coated on the surface of concrete.SELECTED DRAWING: None
【課題】熟練した施行業者でなくても、容易に塗装できるコンクリート用塗装材料の提供。【解決手段】セメントと、セメント混和用ポリマと、水溶性セルロースエーテルと、消泡剤とを混合するコンクリート用塗装材料。コンクリート用塗装材料においては、セメント１００質量部に対してセメント混和用ポリマが、ポリマ固形分で５〜１５質量部、水溶性セルロースエーテルが、０．３〜０．５質量部。消泡剤が、０．１〜０．５質量部で添加するコンクリート組成物。更に、このようなコンクリート用塗装材料を、コンクリート用塗装材料に対し水／粉体比で６０〜９０質量％となる様に水と混合して、コンクリート表面に塗布するコンクリート用塗装材料。【選択図】なし
