Zusammenfassung:	To provide a foaming agent composition for civil engineering work that is excellent in foamability and stability and can suppress elution of environmental contaminants such as hexavalent chromium.SOLUTION: A foaming agent composition for civil engineering work containing a reducing agent containing a sulfur atom and one or more surfactants selected from an anionic surfactant and a nonionic surfactant is a liquid composition containing water. In the foaming agent composition for civil engineering work, the reducing agent containing a sulfur atom is at least one compound selected from hydroxymethanesulfonic acid, hydroxymethanesulfinic acid and salts thereof.SELECTED DRAWING: None 【課題】起泡性及び起泡安定性に優れ、六価クロムなどの環境汚染物質の溶出を抑制できる土木工事用起泡剤組成物を提供する。【解決手段】硫黄原子を含む還元剤、並びにアニオン界面活性剤及びノニオン界面活性剤から選ばれる１種以上の界面活性剤を含有する土木工事用起泡剤組成物であって、水を含有する液体組成物である。硫黄原子を含む還元剤はヒドロキシメタンスルホン酸、ヒドロキシメタンスルフィン酸及びこれらの塩から選ばれる１種以上の化合物である土木工事用起泡剤組成物。【選択図】なし
