JH-1 powdery early strength water reducing agent

When used in environmental conditions where the minimum temperature is no less than -5℃, it can significantly improve the early strength of concrete, and has the functions of reducing water, plasticizing and improving the workability of concrete. It does not contain harmful substances that reduce the later strength of concrete and damage the internal structure of concrete. Does not contain chloride ions and has no rusting effect on steel bars.
1. Scope of application: It can be applied to steam-cured concrete and winter concrete construction projects with early strength or anti-freeze requirements that are constructed under normal temperature, low temperature and negative temperature (the lowest temperature is not lower than -5℃). Including pumped concrete, ready-mixed and cast-in-place reinforced concrete, prestressed concrete, etc.
2. Main performance: complies with GB8076-1997 early strength water reducing agent standard index.
Three. Recommended dosage: 2~4% (accounting for the total amount of cementitious material). The optimal dosage should be determined through experiments. 4. Directions for use: Should be added to the blender together with the gelling materials.
Five. Note: Concrete should be protected by covering early.
6. Packaging: 40kg/bag
