Abstract

To provide a vibration proof (earthquake proof) installation method of a post-installation anchor and a cement mortar composition used therewith, facilitating installation and capable of suppressing occurrence of an anchor drop-out even when damage and aged deterioration and like are created through impact, quake, vibration, and like.SOLUTION: A vibration proof (earthquake proof) installation method of a post-installation anchor configured to insert and anchor an anchor 5 in an installation hole 11 bored in an installation section such as a ceiling surface, a wall surface, and a floor surface made of installed concrete is an installation method of a post-installation anchor filling self-recovery concrete 4 in a gap between the installation hole and an anchor inserted in the installation hole, using a hydrate hardening cement mortar composition, for a cement material, including water and a reactive material selected from alkali-silica, silica fume, and silicofluoride magnesium.SELECTED DRAWING: Figure 1

【課題】施工が容易であり、衝撃・震動・振動等により損傷や経年劣化等が生じた場合であってもアンカーの脱落の発生を抑制することができるあと施工アンカーの耐振（耐震）施工方法及びこれに用いるセメントモルタル組成物を提供する。【解決手段】打設コンクリートから成る天井面・壁面・床面の如き取付部に穿かれる埋設孔１１にアンカー５を挿入して固着させるあと施工アンカーの施工方法において、埋設孔と埋設孔に挿入したアンカーとの間隙に自己修復性コンクリート４を充填するあと施工アンカーの施工方法、及び、セメント材料に、アルカリシリカ・シリカフェーム・ケイフッ化マグネシウムから選ばれる反応性物質と水とを含有する水和硬化物セメントモルタル組成物。【選択図】図１
