SETTING RETARDER AND CONCRETE PLACING JOINT TREATMENT METHOD
To provide a setting retarder and a concrete placing joint treatment method which can achieve five-day week system in a construction site.SOLUTION: A setting retarder constructed to a surface of concrete in concrete placing joint treatment has a function of adjusting duration of a setting retardation action when constructed to the surface of the concrete. The setting retarder may be a super retardation type such that the duration of the setting retardation action when constructed to the surface of the concrete lasts for 72 hours at the maximum.SELECTED DRAWING: Figure 1
【課題】施工現場の週休２日制を実現することができる凝結遅延剤およびコンクリートの打継ぎ処理方法を提供する。【解決手段】コンクリートの打継ぎ処理においてコンクリートの表面に施工される凝結遅延剤であって、コンクリートの表面に施工した際の凝結遅延作用の持続時間を調整可能な機能を有するようにする。コンクリートの表面に施工した際の凝結遅延作用の持続時間が最大７２時間持続する超遅延タイプであってもよい。【選択図】図１
