IMPREGNATION-TYPE DURABILITY-IMPROVING AGENT FOR HARDENED CEMENT BODY
To provide an impregnation-type durability-improving agent for hardened cement body, which is capable of imparting sufficient waterproofness to cement body during its air curing, and is capable of enhancing the strength of hardened cement body.SOLUTION: An impregnation type durability improving agent for hardened cement body consisting of an aqueous solution, comprises: (A) a salt of a fatty acid having 2 to 10 carbon atoms with a divalent metal and (B) a polyoxyalkylene derivative that is liquid at 25°C and is represented by the following formula (1); wherein R1 is selected from the group consisting of a hydrogen atom and a hydrocarbon group having 1 to 30 carbon atoms, R2 is selected from a hydrogen atom and a methyl group, AO each independently represents one or more selected from oxyalkylene groups having 2 to 4 carbon atoms, and n is the average number of AO groups and represents a number of from 1 to 100.SELECTED DRAWING: None
【課題】本発明の課題は、気中養生において十分な防水性の付与に加え、セメント系硬化体の強度向上を可能とする含浸型セメント系硬化体耐久性向上剤を提供することである。【解決手段】上記課題を解決するために、含浸型セメント系硬化体耐久性向上剤であって、炭素数が２〜１０の脂肪酸と２価金属との脂肪酸２価金属塩（Ａ）と、下記式(１)で表される２５℃で液状のポリオキシアルキレン誘導体（Ｂ）との水溶液からなる含浸型セメント系硬化体耐久性向上剤を提供する。【選択図】なし
