Fields of application

1. The recommended mixing amount is 0.2-0.3% of the cement content (the user can determine the best mixing amount by test), and the water reduction rate is more than 10%, which can significantly improve the workability of concrete, greatly reduce the initial hydration heat of cement, and no corrosion damage to steel bars.
   2.Good compatibility with naphthalene and melamine resin superplasticizers, and the aqueous solution does not precipitate;
   3. The product is green, non-toxic and harmless;

 

usage

Pre-mixed with other dry powder components, then packaged, and mixed with recommended water on site.
The recommended addition amount is 0.20%-0.30% of the cementing material, which should be determined according to the preliminary test of raw materials and construction specifications before use.
