| abstract |
The present invention relates to a room-temperature fast-diameter epoxy cracking injection composition used for repairing cracks in structures built with concrete, wherein vehicle traffic such as concrete and tunnels used in the manufacture of concrete roads, expansion joints of bridges and bridge bearings In order to quickly repair cracks that occur in frequent concrete structures, the wettability of the epoxy crack injection agent is improved so that the permeability is excellent. , It provides a room temperature fast-setting epoxy-based crack injection composition having high adhesive strength and tensile strength, and low curing shrinkage and elongation. |
