Product Description

Product Description

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

 

Advantages

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
