MAINTENANCE METHOD FOR CONCRETE STRUCTURE
To provide a maintenance method for a concrete structure capable of permeating a large amount of durability improving substances into the concrete structure and eliminating stickiness of a surface in an early stage.SOLUTION: A maintenance method of a concrete structure where a solution containing durability improving substances for improving the durability of a target concrete structure is impregnated from a surface of the concrete structure, comprises: a surface moisture content confirming step of measuring a moisture content of the surface of the concrete structure to confirm that the moisture content is 6.0% or less; a thickener mixing step of mixing a thickener obtained by mixing one or two or more kinds selected from a thickener stabilizer and an acrylic acid-based water-absorbing resin into an aqueous solution containing the durability improving substances; and a durability improving substance supplying step of supplying durability improving substances by applying or spraying a predetermined amount of the aqueous solution mixed with the thickener in the thickener mixing step on the surface of the concrete structure.SELECTED DRAWING: None
【課題】コンクリート構造物に耐久性向上物質を大量に浸透させることができるとともに、早期に表面のべたつきを解消可能なコンクリート構造物の保全工法を提供する。【解決手段】対象とするコンクリート構造物の表面から、当該コンクリート構造物の耐久性を向上させる耐久性向上物質を含有する溶液を含侵させるコンクリート構造物の保全工法において、前記コンクリート構造物の表面の含水率を測定して当該含水率が６．０％以下であることを確認する表面含水率確認工程と、前記耐久性向上物質を含有する水溶液に、増粘安定剤及びアクリル酸系吸水性樹脂の中から選ばれた１種又は２種以上を混合した増粘剤を混和する増粘剤混和工程と、前記増粘剤混和工程で前記増粘剤が混和された水溶液を前記コンクリート構造物の表面に所定量塗布又は噴霧して供給する耐久性向上物質供給工程と、を備える。【選択図】なし
