The present invention provides a crack-reducing acid-resistant polymer mortar composition with excellent workability containing a thickener consisting of a mixture of a cellulosic organic thickener and attapulgite, a porous inorganic thickener, a powder-type high fluidizer and a moisturizing material, and a cross-section repair and reinforcement method using the same More specifically, it uses attapulgite, a porous inorganic thickener, to absorb moisture from the existing concrete sewer pipe to prevent sagging at the beginning of pouring, and simultaneously use sacran (moisturizing material) to mortar during plastering work. Provided are a crack-reducing acid-resistant polymer mortar composition with excellent workability that can express excellent workability by reducing frictional force with the mortar, and a cross-section repair and reinforcement method using the same. |
