1. Title
Output Increase & Strength Enhancement with Unchanged Mix Design for P·O42.5 Cement — ZS-High-Efficiency Enhanced Cement Grinding Aid Industrial Trial
2. Customer Background
A cement company in Qinshan, Zhejiang, operates a φ4.2×13.0m closed-circuit mill (Mill No. 3) producing P·O42.5 cement. The customer supplies high-end ready-mix plants and key construction projects with stringent strength requirements. The customer sought to increase mill output and cement strength while keeping the mix design unchanged.
3. Pain Points & Challenges
Strength Enhancement Required: The high-end market demands continually improving P·O42.5 cement strength.
Mill Output Bottleneck: Mill throughput was approximately 190 t/h, with room for capacity optimization.
Mix Design Must Remain Unchanged: The customer required output and strength improvement without adjusting clinker or SCM proportions.
4. Solution
From July to December 2025, Shengchuan's technical team conducted a ZS-High-Efficiency Enhanced Cement Grinding Aid industrial trial on Mill No. 3 (φ4.2×13.0m closed-circuit). As Shengchuan's flagship enhanced-series product, its core function is to deeply stimulate late-stage C₂S hydration through a high-purity TIPA/DEIPA long-acting alkanolamine system while simultaneously improving grinding efficiency.
Grinding Aid Model: ZS-High-Efficiency Enhanced Cement Grinding Aid
Dosage: 500g/t (0.05%)
Mix Proportion: Clinker 74%, desulfurized gypsum 5.5%, fly ash 8%, steel slag 9.5%, steel slag powder 3%, externally added slag powder 8% (unchanged throughout)
Trial Method: 24-hour baseline comparison + 16-hour transition + 168-hour continuous trial production

6. Case Summary
With the cement mix design completely unchanged, the adoption of ZS-High-Efficiency Enhanced Cement Grinding Aid increased mill output from 190 t/h to 212 t/h (↑11.6%), mill discharge 3-day strength by 3.7 MPa, and mill discharge 7-day strength by 6.9 MPa. Silo inlet strength improved simultaneously. While maintaining fineness control, the product achieved the dual objectives of output increase and strength enhancement, making it especially suitable for cement production lines with high 28-day strength requirements.
7. Application Recommendations
Suitable Conditions: P·O42.5 and above high-grade cement production lines with high 28-day strength requirements, seeking output increase and strength enhancement without mix design changes.
Recommended Dosage: 500g/t.
Expected Results: Output increase of 10%–15%; 28-day strength improvement of 5–8 MPa.
