HKZS-M50 Support Mortar
Performance
The product implements the technical requirements of national and railway industry standards such as TB/T2331-2013 " Basin Bearing for Railway Bridge".
1．It has excellent fluidity, no segregation, no bleeding, no need to vibrate, and good workability;
2．The water consumption range is wide, and the appropriate fluidity and final strength can be obtained by adjusting the mixing water consumption;
3．The loss of fluidity is small and can be operated in long time;
The dual effects of plastic expansion and hardening expansion ensure an effective bearing surface with early strength and high strength.
