Using IN Precast Concrete:
Accelerator powder is a dark gray powdery powder made of clinker, soda ash, thickener, etc. through modification.
The admixture has a rapid setting and rapid hardening effect on cement. The cement paste containing a proper amount of accelerator powder can quickly set and harden, has higher early strength and late strength, and can maintain other properties of cement. Ideal accelerator for concrete and mortar.
Concrete Accelerator Powder Benefits
● It does not contain calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of reinforcing steel present in the concrete.
● Use as a replacement for steam curing to save energy costs.
● Increase early strengths and allow faster rotation of molds to increase production per day.
● Use as a replacement for Type III cement.
● Cold weather concreting: It is an effective hardening accelerator where high early strength concrete is desired and the use of calcium chloride is prohibited.
- It is an effective hardening accelerator where high early strength concrete is desired and the use of calcium chloride is prohibited.
Using in Others
● Concrete mixture mixed with the accelerator powder is highly viscous, which can increase the one-time shot thickness of the concrete and reduce the rebound amount. In general, the rebound amount of the sprayed concrete is less than 20%, and the rebound amount of the sprayed concrete Less than 15%.
● Concrete mixed with accelerator powder can produce expansion effect during the hardening process, and improve the compactness, impermeability and durability of concrete.
● The quick-setting powder has low alkalinity and is less corrosive to the human body.
