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 retaining agent 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, reduce bleeding, and reduce slump loss. .
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.
iv. packaging and storage
this product is packed in plastic bags, 50kg/bag, liquid 200kg/barrel. storage period is 2 years. </p
