High efficient concrete retarder water reducing agent sodium gluconate
Concrete retarder water reducing agent is retarding superplasticizer water reducing component,
and It’s water-reducing rate, the effect of enhancing is significant, can significantly improve
the fluidity and workability of concrete.
The technical performance of concrete retarder as follows:
Technical performance: | |
Appearance | Brown liquid |
Solid content | ≥ 92% |
Fineness | 0.15mm sieve residue <15% |
PH value | 7-9 |
Water reducing rate | 15-25% |
Dosage | 0.75 - 1.5% (recommend 1.0% ) |
The initial slump of concrete | Increased more than 15cm |
The corrosion on steel | No |
The approach of using | Especially suitable to significantly reduce the amount of cement pumping performance with special requirements, commodities, crowd-state, large volume concrete foundation and RCC |
High efficient concrete retarder water reducing agent sodium gluconate
Use:
1.Powder can be added directly with the cement, sand, gravel together in the blender,First dry mix, then wet mix with water, stirring the same time with ordinary concrete.
2.Recommended dosage (in plastic timber weight) : 0.8 to 2.0%.
3.When small quantities of concrete artificial stirring, the powder should be added to the mixing water after water applied (after the dissolution of the goods "carrier" materials precipitation is normal).
Concrete additives with improvement corrosion resistance,
and other products.
