OS-53C has super slump retention effect, as 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-53C can be applied to:
Various types of strength grade ready-mixed concrete
High strength, Ultra high strength concrete
Various types of concrete of the long distance transportation and longtime slump retention
OS-53C 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:
Super concrete slump retention effect
Strong late water reducing release function
Improved the flow ability of concrete
Improve compressive strength, durability of concrete.
Very low alkali content, no chloride ions and corrosion components of steel in reinforced concrete.
OS-53C is a high performance polycarboxylate water-reducing admixture with Super concrete slump retention effect and strong late water reducing release function, The product can be used mixed with other high water reducing type PCE superplasticizer (such as OS-41A, OS-42A etc.).
The recommended dosage is 0.4-1.5% 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 other water reducer of PCE, 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.
