1. Scope of application
Suitable for construction in high-temperature seasons, long-distance transportation, ultra-elevation pumping to reduce concrete slump loss, on-site pouring of concrete, large-volume concrete, self-leveling concrete, high-strength, high-performance concrete, Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement, composite Portland cement (i.e. the six major cements).
2. Implementation standards: GB8076-1997, GB50119-2003.
3. Performance and characteristics
1. Water reduction rate: 2.5-3.5%
2. Dosage: C×0.3-0.5%
3. Plastic retention As a plastic-preserving component in admixture products, it can effectively improve the plastic-preserving effect of concrete during transportation and pumping. It also has a retarding effect, which can significantly improve the workability of concrete and reduce bleeding and slump loss. Small.
4. How to use: When the product is mixed with a dosage of 0.3% and a naphthalene-based high-efficiency water-reducing agent with a dosage of 0.75%, the initial slump is 170-180mm, and the slump and fluidity are lost within 2 hours. Small.
5. Fresh concrete has good workability, good cohesion, no segregation, and no bleeding.
6. Retardation performance: delay the initial and final setting time for >7 hours (extended with the plastic retention time)
7. The durability indicators of concrete such as impermeability, freeze-thaw resistance, and carbonation resistance are greatly improved.
8. This product is non-toxic, non-flammable and has no corrosion effect on steel bars.
4. Packaging and Storage
This product is packed in plastic bags, 50kg/bag, 200kg/barrel of liquid. Storage period is 2 years. </p
