At Huahai Concrete Admixture , we specialize in developing high-performance, customized cement grinding aids that solve specific production challenges for our clients. We don't believe in one-size-fits-all solutions. Our approach is to deeply understand our customer's raw materials, production goals, and economic targets to formulate the perfect grinding aid for their unique needs.

This case study showcases how our technical team delivered a tailored solution for a cement plant aiming to optimize two different cement types—one for cost reduction and another for enhanced strength.

Client Profile & Production Challenges

Our client, a modern cement plant, was producing two primary types of cement with distinct performance requirements.

Cement A: A cost-effective cement where the primary goal was to reduce the clinker factor without compromising strength or increasing energy consumption.

Original Mix Design: Clinker (83%), Gypsum (4%), Limestone (12.5%), Fly Ash (0.5%)

Original Strength: 2-day: 18 MPa | 28-day: 38 MPa

Client Goal: Reduce clinker usage, increase limestone by 3%, and maintain original 2-day and 28-day strength without increasing power consumption.

Cement B: A high-performance cement where the goal was to achieve a significant strength boost.

Original Mix Design: Clinker (90.5%), Gypsum (4%), Limestone (5.5%)

Original Strength: 2-day: 22.5 MPa | 28-day: 43.5 MPa

Client Goal: Increase 2-day strength to 28 MPa and 28-day strength to 58 MPa without increasing grinding power consumption.

Initial Grinding Conditions:

Blaine Value: 3200 cm²/g

Residue at 45 microns: 12%

Our Customized Solution & Technical Approach

Our engineers conducted a thorough analysis of the client's raw materials and grinding process. Recognizing the conflicting goals for each cement type, we developed two specialized grinding aid formulations from our CGA® series.

For Cement A: CGA®-CLF (Clinker Reduction Formula)
This formula was engineered to enhance the grindability of the cement mix, particularly the harder clinker particles, allowing for a more efficient particle size distribution. Its powerful surfactants reduced agglomeration and coating in the mill, enabling the client to successfully incorporate more limestone while maintaining fineness and strength.

For Cement B: CGA®-HP (High-Performance Strength Enhancer)
This advanced formulation was designed not only to improve grinding efficiency but also to act as a powerful strength enhancer. CGA®-HP contains functional monomers that actively participate in hydration chemistry, accelerating early strength development and contributing to the formation of a denser microstructure, resulting in vastly superior ultimate strength.

Remarkable Results Achieved

After the application of our customized grinding aids, the client reported outstanding results that exceeded their expectations.

Results for Cement A:

New Optimized Mix Design: Clinker (80%), Gypsum (4%), Limestone (15.5%), Fly Ash (0.5%)

Strength Maintained: 2-day: 18.5 MPa | 28-day: 39 MPa

Power Consumption: Remained unchanged.

Client Benefit: Significant reduction in raw material cost due to the 3% lower clinker factor, achieved without any loss in cement performance.

Results for Cement B:

Mix Design: Unchanged (Clinker 90.5%, Gypsum 4%, Limestone 5.5%)

Strength Significantly Increased: 2-day: 28.8 MPa | 28-day: 59 MPa

Power Consumption: Remained unchanged.

Client Benefit: Enabled the production of a new, high-value, premium-grade cement that could command a better market price, all without investing in new equipment or increasing energy costs.

Conclusion

This project is a perfect example of how a tailored technical approach to grinding aids delivers far greater value than standard chemical products. By partnering with Huahai , the client successfully:

Reduced production costs for one product line.

Created a new high-strength, high-margin product for another.

Achieved both goals with no increase in energy consumption.
