SETTING RETARDER AND PLACING JOINT TREATMENT METHOD FOR CONCRETE
To provide a setting retarder that achieves efficiency of construction joint work, and a placing joint treatment method for concrete.SOLUTION: A setting retarder applied to a surface of concrete in placing joint treatment of the concrete has a function of exhibiting a predetermined setting retarding action by staying on the surface of the concrete located in a position to which the setting retarder is applied right after the placement. The setting retarder contains a base compound having the setting retarding action, wherein a relative density of the base compound may be larger than that of bleeding water. Moreover, the setting retarder may have a component that has high viscosity by reacting with the bleeding water or the concrete.SELECTED DRAWING: Figure 1
【課題】打継ぎ処理作業の効率化を図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、打込み直後のコンクリートの表面に施工した際に、施工した位置のコンクリートの表面に留まって所定の凝結遅延作用を発揮する機能を有するようにする。凝結遅延作用を有する主剤を含有し、この主剤の比重はブリーディング水よりも大きいものでもよい。また、ブリーディング水またはコンクリートと反応して高粘性化する成分を有してもよい。【選択図】図1
