INORGANIC ANCHOR MATERIAL AND ANCHORAGE METHOD OF ANCHOR BAR USING ANCHOR MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an inorganic anchor material using ultra rapid hardening cement capable of goodly maintaining adhesive strength of the anchor material using the ultra rapid hardening cement to a concrete structure even under high temperature environment and an anchorage method of anchor bar using the material.SOLUTION: There is provided an inorganic anchor material containing ultra rapid hardening cement, silica fume, powder mainly containing lithium salt and an aggregate and water with 0.5 to 5.0 pts.mass of the silica fume and 0.5 to 5.0 pts.mass of the lithium salt based on 100 pts.mass of the ultra rapid hardening cement and having adhesive strength of an anchor bar at 20°C and 80°C of 20 N/mmor more measured according to "post application anchor test method" of JCAA.SELECTED DRAWING: None
