This paper reports on the influence of environmental temperature on pull-out properties of post-installed adhesive anchor. And the follow conclusions were found. There is relationship between the maximum pull-out load of post-installed adhesive anchor and the compressive strength of concrete at temperatures up to 80°C depends on the adhesive type.* 1 建築研究所材料研究グループ 主任研究員・博士(工学) (〒 305-0802 つくば市立原 1) * 2 建築研究所材料研究グループ 研究員・博士(工学) * 3 建築研究所材料研究グループ シニアフェロー・Ph.D.
