ZS-High-Dosage Fly Ash Cement Grinding Aid
1. Product Introduction
What is ZS-High-Dosage Fly Ash Cement Grinding Aid?
ZS-High-Dosage Fly Ash Cement Grinding Aid is specially formulated for P.F and P.C fly ash composite cements with fly ash content of 30% to 60%, and complies with GB/T 26748 standard. The formula incorporates a fly ash vitreous activation system and long-lasting strong alcohol amines, specifically addressing industry pain points such as low fly ash activity, poor early strength, insufficient 28-day strength, easy grinding mill coating due to fly ash's light texture, and high water demand of finished products.
How Does It Work?
Particle Dispersion: Neutralizes static charges on cement particle surfaces during grinding, preventing agglomeration and reducing the "cushioning effect" inside the mill.
Grinding Efficiency: Reduces the surface hardness of slag particles, refines the powder, optimizes the effective strength particle range of 3-32μm, and reduces the power consumption per ton of cement.
Strength Activation: The active components chemically interact with cement phases (C₃S, C₂S), promoting more complete hydration and contributing to both early and late strength development.

5. Frequently Asked Questions
Q: How is the optimal dosage determined?
A: The recommended range is 300g – 800g per ton of cement. Exact dosage depends on clinker grindability, mill type, and fly ash characteristics. Our technical team can assist with mill trials.
Q: Will adding this product increase the water demand of the cement?
A: No. It contains self-dispersing water-reducing components, which actually reduce the standard consistency water requirement of fly ash cement, resulting in better concrete fluidity.
Q: Will the problems of ball coating and fly ash dust agglomeration in the mill be improved?
A: Yes, significantly. The agent neutralizes the static electricity of the fly ash, preventing fine powder from clumping and sticking to the lining plates and steel balls. Mill hourly rate increases by 9%-19%, and grinding power consumption decreases by 7%-14%.
Q: How should the product be stored?
A: Store in a sealed plastic container at room temperature. Protect from freezing in winter. Do not store with strong acid additives. Shelf life: 6 months.

7. Usage Guidelines
Calibration: Install a dedicated metering pump and calibrate to target dosage. Addition point: clinker feed belt or mill feed port.
Application Point: Apply evenly onto the clinker feed before entering the mill.
Monitoring: Track mill amperage, production rate (t/h), and cement quality (Blaine, residue).
Note: We provide methods for detecting and controlling the feed rate.
