PRIMER FOR CEMENT PLACING JOINT, AND PLACING-JOINT METHOD FOR CEMENT
PROBLEM TO BE SOLVED: To provide a primer for cement placing joint that offers high bonding strength even when time between application and casting of uncured cement mixture for the placing joint is long (when casting start time management is lenient) and integrity between existing and new cured bodies is hardly affected even when water circulated to the placing joint surface after casting; and to provide a placing-joint method for cement that offers high bonding strength even when time between application and casting of uncured cement mixture for the placing joint is long and integrity between existing and new cured bodies is hardly affected even when water circulated to the placing-joint surface after casting.MEANS: A primer for cement placing joint comprises mainly of a specified organic compound, desirably an alkali-stable organic compound.SELECTED DRAWING: None
【課題】塗布から打ち継ぐ未硬化のセメント混練物の打設までの時間が長い場合であっても（緩い打設開始時間の管理であっても）高い接着力が得られ、更に、施工後打継ぎ面に水が回った場合においても新旧硬化体の一体性が損なわれ難いセメント打継ぎ用プライマーを提供すること。また、塗布から打ち継ぐ未硬化のセメント混練物の打設までの時間を長くしても高い接着力が得られ、更に、施工後打継ぎ面に水が回った場合においても新旧硬化体の一体性が損なわれ難いセメントの打継ぎ方法を提供すること。【手段】特定の有機化合物を主要成分とするセメント打継ぎ用プライマー。アルカリ安定性のものであると好適である。【選択図】なし
