OS-41A is an ultra-high water reducing effect of polycarboxylate high performance water reducing admixture.
It was developed through our own advanced synthetic technologies. The modified carboxylate copolymer as the main component, the products comply with GB 8076-2008 "Concrete Admixtures".
Range of Applications
OS-41A can be applied to:
- Various types of strength grade ready-mixed concrete
- High strength, Ultra high strength concrete
- Self-compacting concrete
- Various types of pumping concrete, precast concrete, etc.
- Low water/cement ratio, High early strength concrete
OS-41A in concrete by surface adsorption, the space steric effect on the cement particles, and charge repulsion effects,
and thus plays to stop the temporary cement hydration.
This product has the following outstanding advantages:
- Ultra high water-reducing effect
- Good concrete slump retention effect
- Greatly improved the flow ability of concrete
- Significantly improve compressive strength of concrete, especially early strength
- Very low alkali content, no chloride ions and corrosion components of steel in reinforced concrete
Specific gravity @20ºC,
Total alkali content
Packaging & Storage
- OS-41A is available in 200 Kg plastic Drum, 1m3 IBC and Flexi Bag.
- Storage at 0-40ºC, to avoid direct sunlight or freezing.
- The shelf-life is normally 12 months. It is tested eligibility and then used when it exceeds.
- OS-41A is a high performance polycarboxylate water-reducing admixture with ultra-high water-reducing function; the product can be used after dilution, or directly added to the concrete mixers with water.
- The recommended dosage is 0.2-1.0% of the weight of cementitious materials,
The optimum dosage should confirm by testing. And should be appropriately extended mixing time in order to achieve the best results.
- This product can be used together with retarder, defoamer, air-entraining agent, and lignin sulfonate and so on. It cannot be used together with the naphthalene superplasticizer.
- This product has better adaptability to various types of cement, fly ash, slag powder and other types of grinding powder cementing material of concrete.
This product does not contain toxic substances, non-flammable, and no significant corrosion. Do not contact with the skin for a long time, if contact with skin or eyes, rinse immediately with water. Swallowing should seek medical treatment
