CEMENT COMPOSITION SURFACE FINISHING METHOD
To provide a cement composition surface finishing method which can secure a usable life while reducing a waiting time to the finishing operation of a cement composition surface.SOLUTION: A cement composition surface finishing method has: a first stirring step of stirring a pre-kneaded cement composition in a stirrer before placement; a hardening accelerator addition step of adding a CSH-based hardening accelerator made into a liquid or slurry shape in the stirrer and blended with a strength promotion assistant or a CSH-based hardening accelerator and a strength promotion assistant after the first stirring step; a second stirring step of stirring the cement composition after the addition at a stirring rate higher than that of the first stirring step; a placing step of placing the cement composition after the addition; and a finishing step of finishing a surface of the placed cement composition after the addition.SELECTED DRAWING: Figure 1
【課題】セメント組成物表面の仕上げ作業までの待ち時間を短縮しつつも可使時間を確保することが可能なセメント組成物の表面仕上方法を提供する。【解決手段】予め練り混ぜられたセメント組成物を、打設前に攪拌機内で撹拌する第一攪伴ステップと、前記第一攪伴ステップの後に前記撹拌機内において液状又はスラリー状をなし、強度増進助剤が配合されたＣＳＨ系の硬化促進剤、または、ＣＳＨ系の硬化促進剤及び強度増進助剤、を添加する硬化促進剤添加ステップと、前記添加をした添加後セメント組成物を前記第一攪伴ステップの攪伴速度よりも速く撹拌する第二攪伴ステップと、前記添加後セメント組成物を打設する打設ステップと、前記打設した前記添加後セメント組成物の表面を仕上げる仕上ステップと、を有する。【選択図】図１
