EXFOLIATION PREVENTION STRUCTURE FOR CONCRETE PIECE
PROBLEM TO BE SOLVED: To provide an exfoliation prevention structure for a concrete piece that has less load to environment, high strength, and good workability.SOLUTION: The exfoliation prevention structure for a concrete piece includes an undercoat layer that is formed on a concrete base material and formed by using an undercoat paint composition containing a water soluble resin composition, an intercoat layer that is formed on the undercoat layer, configured to have a mesh sheet, and formed by using an intercoat paint composition containing a water soluble resin composition, and a finishing coat layer that is formed on the intercoat layer and formed by using a finishing coat paint composition containing a water soluble resin composition. The coefficient of extension for a coated film formed by the intercoat paint composition is 50 to 250%, and the tensile strength is 5 to 18 N/mm. The ultimate tensile strength of the mesh sheet is 2,500 to 4,300 N/50 mm.SELECTED DRAWING: None
【課題】環境への負荷が少なく、強度が高く、施工性が良好なコンクリート片の剥落防止構造を提供すること。【解決手段】コンクリート片の剥落防止構造は、コンクリート基材上に形成され、水溶性樹脂組成物を含む下塗塗料組成物により形成された下塗層と、前記下塗層上に形成され、メッシュシートを含んで構成されるとともに、水溶性樹脂組成物を含む中塗塗料組成物により形成された中塗層と、前記中塗層上に形成され、水溶性樹脂組成物を含む上塗塗料組成物により形成された上塗層とを含み、前記中塗塗料組成物により形成される塗膜の伸び率が５０〜２５０％、かつ、抗張力が５〜１８Ｎ／ｍｍ２あり、メッシュシートの引張強度が２，５００〜４，３００Ｎ／５０ｍｍである。【選択図】なし
