ZS-General-Purpose Cement Grinding Aid
1. Product Introduction
What is ZS-General-Purpose Cement Grinding Aid?
ZS-General-Purpose Cement Grinding Aid is a high-performance, general-purpose cement grinding aid, primarily suitable for Portland cement, ordinary Portland cement, composite Portland cement, fly ash Portland cement, pozzolanic Portland cement, and slag Portland cement. It can also be used in masonry cement. This product aims to improve grinding efficiency, increase mill output, enhance cement strength, and improve the mechanical properties of the final cement product.
How Does It Work?
Particle Dispersion: ZS-General-Purpose Grinding Aid neutralizes static charges on cement particle surfaces during grinding, preventing agglomeration and reducing the "cushioning effect" inside the mill.
Grinding Efficiency: By keeping particles separated, it allows the grinding media to work directly on the clinker, reducing energy consumption per ton.
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.
Why ZS-General-Purpose Grinding Aid from Shengchuan?
20 Years of Focused R&D: Built on Zhongsen Holding Group's deep expertise in energy-saving and environmental protection for the cement industry.
43+ National Patents: Protected by extensive intellectual property in green cement additives and composite cementitious materials.
Top University Partnerships: Ongoing industry-academia cooperation with Tsinghua University, University of Science and Technology Beijing, and University of Jinan, along with an academician workstation in Shandong Province.
National Standards Contributor: Participation in national key R&D projects and contribution to 6 national industry standards for cement and concrete.
Proven in 20+ Markets: Since 2006, validated in over 20 markets including China, Africa, Southeast Asia, Central Asia, and the Middle East.

5. Frequently Asked Questions
Q: What types of cement is ZS-General-Purpose Grinding Aid suitable for?
A: It is suitable for Portland cement, ordinary Portland cement, composite Portland cement, fly ash cement, pozzolanic cement, slag cement, and masonry cement. For specialized types such as oil well cement, please contact our technical team for a custom formulation.
Q: How is the optimal dosage determined?
A: The recommended range is 500g – 1000g per ton of cement. Exact dosage depends on clinker grindability, mill type, target fineness, and SCM content. Our team can assist with industrial trials to find your economic optimum.
Q: Does Shengchuan have real case studies for this product?
A: Yes. In a Yunnan P·O 42.5 plant, clinker usage dropped from 86.6% to 80.0% while maintaining 28-day strength. In a Guangxi M32.5 plant, SCM usage increased from 30% to 35%, and both early and late strength improved.
Q: What is the difference between this and the High-Efficiency Enhanced series?
A: The General-Purpose series is optimized for balanced performance across standard cement types. The High-Efficiency Enhanced series contains additional strength-activating components, ideal for plants pushing for maximum clinker replacement or requiring higher late-age strength.
Q: How should the product be stored?
A: It is a weakly alkaline liquid. Store in a sealed plastic container at temperatures between -5℃ and 40℃. Shelf life: 12 months.
Q: What are the main components?
A: The product is mainly composed of alcohol amines, polymeric polyols, and sugars, with a small amount of inorganic salts. It is dark brown, opaque, odorless, and does not harm human health or cement concrete properties.
6. Application Scope
Application | Benefit |
Ball Mill / Vertical Mill Grinding | Improved throughput, lower energy intensity |
Blended Cement Production | Enables higher SCM loading while maintaining strength targets |
High-Volume Limestone Cement | Enhanced particle size distribution for improved workability |
General Ready-Mix Concrete Supply | Consistent cement quality improves concrete batching predictability |
7. Usage Guidelines
Calibration: Install a dedicated metering pump. Calibrate it to the target dosage (500g – 1000g/ton of cement). Direct metering can be used when no lift is required; otherwise, a two-stage pumping method is recommended. The addition point should be on the clinker feed belt or at the mill inlet.
Application Point: Apply the grinding aid evenly onto the clinker feed before the mill to ensure uniform dispersion.
Monitoring: Track mill amperage, production rate (t/h), cement quality (Blaine, residue on 45µm sieve), and critically, 28-day compressive strength to quantify the improvement.
Note: We provide customers with methods for detecting and controlling the feed rate.
