1. Title
Clinker Reduction & Mix Cost Optimization for P·C Cement — ZS-PPC Cement Grinding Aid Industrial Trial
2. Customer Background
A cement company in Shanxi operates a 3.8×13m mill producing P·C42.5R and P·C42.5 cement, with locally abundant pozzolanic SCM resources. The customer previously used a combination of "500g/t grinding aid + 500g/t enhancer" and sought a more cost-effective solution that could both reduce clinker usage and optimize overall mix costs.
3. Pain Points & Challenges
High Mix Costs: P·C42.5 mix cost approximately 121.86 RMB/t and P·C42.5R approximately 131.93 RMB/t, presenting clear cost reduction potential.
Elevated Clinker Usage: P·C42.5R clinker at 70% and P·C42.5 clinker at 64%, with room for further reduction given abundant pozzolan resources.
Strength Must Be Guaranteed After Clinker Reduction: After reducing clinker by 4%–5%, both 3-day and 28-day strength must continue to meet national standards.
4. Solution
In May 2024, Shengchuan's technical team conducted a ZS-PPC Cement Grinding Aid industrial trial on the customer's 3.8×13m mill. Designed specifically for pozzolanic Portland cement systems, the product's core function is to enhance pozzolanic glassy phase activation, maintaining or even improving strength while reducing clinker usage.
Grinding Aid Model: ZS-PPC Cement Grinding Aid
Dosage: 800g/t (replacing the original 500g/t grinding aid + 500g/t enhancer combination)
Mix Proportion Adjustment: P·C42.5R clinker from 70%→65%; P·C42.5 clinker from 64%→60%
Trial Period: May 18–26, 2024

5.3 Economic Benefit Estimation
Based on annual production of 1 million tons of P·C42.5 cement, with mix cost reduced by 5.41 RMB/t:
Annual Mix Cost Savings: 1,000,000 tons × 5.41 RMB/t = 5.41 million RMB
6. Case Summary
After adopting ZS-PPC Cement Grinding Aid, P·C42.5 clinker usage was reduced from 64% to 60% (↓4 percentage points) with mix cost savings of 5.41 RMB/t; P·C42.5R clinker usage was reduced from 70% to 65% (↓5 percentage points) with mix cost savings of 3.47 RMB/t. While reducing clinker usage, cement strength was maintained or improved. This case represents one of the most comprehensive economic benefit datasets among Shengchuan's industrial trials for "clinker reduction + cost optimization."
7. Application Recommendations
Suitable Conditions: P·C42.5/P·C42.5R cement production lines with abundant pozzolan, fly ash, or other SCM resources, seeking systematic mix cost reduction.
Recommended Dosage: 800g/t.
Expected Results: Clinker usage reduction of 4–5 percentage points; mix cost reduction of 3–6 RMB/t.
