Product performance characteristics:
1.This product has characteristics of high dispersion and low gas content,mixing concrete can significantly increase the mobility to facilitate the construction of concrete.
2. High water-reducing,up to 15-23%,while maintaining the slump under the same conditions,can significantly increase the strength of concrete of various ages.
3. While maintaining the original design strength and slump,can save 10-20%of cement.
4. Chloride ion content is very low,no corrosion effect.
5. Mixing the products,can significantly improve the workability of concrete. The performance of reinforcement strengh,anti-carbonation,anti-remeability has clearly improved.
