Description:
The product is inorganic mixture, fast harden\ High intensity \ micro-expansion, Environment-friendly. do not need to warm up in normal condition (20℃\68℉ \ 70 % Humidity). Mixed with water is available. Avoid crack due to partial warmed, which reduce the working time of rail spike. Constriction at -10℃\ 14℉ is available. Well performance after 2 million times destructive test
Applications:
1, It can be used in railway: rail spike anchoring of the concrete railroad crosstie \ crosstie of bridge. It can be used in anchoring of installed bridge bonded joined and the foundation bolt of instrument.
2, It can be used in railway\ tunnel \ channel \ coal mine \ Strengthen of bridge pier \ anti-crack of house \ Metallurgic mine etc. fast construction for anchorage of underground construction with anchoring component. In order prevent stone drop.
3. It can be used in the Strengthen of the concrete construction with reinforcing steel bar. And satisfy the weld of the reinforcing steel bar.
