ZS-PPC Cement Grinding Aid

ZS-PPC Cement Grinding Aid

1. Product Introduction

What is ZS-PPC Cement Grinding Aid?

ZS-PPC Cement Grinding Aid is a specialized grinding aid designed for Portland Pozzolana Cement (PPC) compatible with high-pozzolan blending systems incorporating fly ash, volcanic ash, pumice, diatomaceous earth, and similar materials. It complies with the GB/T 26748 standard. Its core formulation enhances the activation of the glassy phase in pozzolanic materials, effectively addressing issues such as low raw material reactivity, poor early-stage strength, insufficient strength margins at 28 days, tendencies toward grinding-mill clogging, and excessive water demand.

How Does It Work?

This multifunctional additive utilizes a composite of alkanolamines to provide both grinding aid and activation effects, overcoming the limitations of conventional agents like TEA. When combined with other grinding aid components, it effectively reduces cement fineness and optimizes particle size distribution. Furthermore, sulfonic acid modification mitigates the increased water demand typically associated with finer cement, thereby enhancing strength upon application. Additionally, components that optimize the morphology of cement hydration products reduce porosity and increase density, further boosting the cement's strength.

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, target fineness, and SCM content. Our technical team can assist with mill trials.

Q: Can ZS-PPC cement grinding aid and composite cement grinding aid be used interchangeably?

A: Not recommended. Composite cement grinding aids focus on activating large amounts of slag and fly ash, whereas the PPC formula is designed for pozzolan activation, water demand reduction, and low chloride content. Interchanging them would lead to insufficient strength gain and abnormal water demand.

Q: Will the later-stage strength decline when stored in high-temperature regions?

A: No. ZS-PPC utilizes a long-acting, strength-enhancing alcohol-amine system that sustains secondary hydration. The 28-day strength steadily increases—without regression—even under high-temperature conditions associated with cement silo storage and maritime transport.

Q: Does this product contain chlorides?

A: No. Chloride content is ≤0.1%, safe for reinforced concrete applications.

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.

6. Application Scope

Application	Benefit
PPC Cement Production for Export	Meet overseas testing standards, avoid goods being detained due to insufficient strength
Grinding Stations with High Fly Ash/Volcanic Ash Content	Increase volcanic ash content by 5%-12%, reduce clinker consumption

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.
