Gravity mortar is a specialized filling mortar developed for the installation of bridge deck ancillary works on passenger-dedicated lines. It is easy to use and simple to operate, quickly self-leveling and grouting through gravity action. It accelerates construction progress and enhances the fatigue resistance of wind barriers. Main applications
1. Filling for the installation of base plates for wind barriers; 2. Filling for the installation of base plates for noise barriers;
3. Filling for the installation of base plates for utility poles; Fluidity, mm ≥360
