Inorganic injection-type anchor
- Adhesion strength: It can achieve a tensile force exceeding the yield strength of the anchor bar with an effective length of 7 d.a. - Hardening performance: It hardens in 24 hours due to the use of special cement. - Workability: Being in a capsule type, simply immersing it in water ensures a constant water ratio, making the mixing process smooth. - Constructability: Due to its high viscosity, there is minimal sagging of the injected mortar during horizontal and upward construction. - Corrosion resistance: The entire surface of the anchor bar is covered with anchor fixing material (mortar), providing excellent corrosion resistance. - Safety: As it primarily consists of cement mortar, it is non-combustible and does not contain harmful substances.

Applications/Examples of results
For the installation of anchors in structures such as tunnels, bridges, and box culverts that require horizontal and upward construction.
Detailed information
-
The compressive strength management value is 50 N/mm² or higher. Curing period is 7 days (20°C).
-
The number of anchor installations possible in the left table is based on a drilling diameter of bolt diameter + 10mm, a drilling depth of 7 times the bolt diameter, and using one dedicated cartridge filled and mixed with two SR injection capsules, with a surplus rate of 20%, as a guideline for the number of installations.
