Product DescriptionIntroductions
OS-42A is a 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-42A 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
Advantages
OS-42A in concrete by surface absorption, 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:
High water-reducing effect
Good concrete slump retention effect
Greatly improved the flow ability of concrete
Good adaptability to concrete
Improve compressive strength, durability of concrete
Very low alkali content, no chloride ions and corrosion components of steel in reinforced concrete

Usage
OS-42A is a high performance polycarboxylate water-reducing admixture with 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 result.
This product can be used together with retarder, defoamer, air-entraining agent, and lignin sulfonate and so on. Itcannot be used together with the FDN 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.
Safety
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.
