Concrete is the backbone of modern construction, but its performance depends heavily on the quality of additives used. The PC-826 Slump Retention Polycarboxylate Superplasticizer, developed by Shijiazhuang Yaguan New Material Technology Co., Ltd., represents a breakthrough in concrete technology. This article explores its features, technical specifications, applications, and the company's commitment to innovation and sustainability.
Product Features: Precision and Performance
The PC-826 superplasticizer is engineered to address critical challenges in concrete construction. Its high plasticity ensures slump retention, extending the working time of concrete and reducing flow loss. This is particularly beneficial in large-scale projects where prolonged workability is essential. The high dispersion capability allows for rapid adsorption, minimizing mixing time and improving efficiency. Additionally, its high durability enhances the compaction of hardened slurry, reducing shrinkage, creep, and cracking. The product is also environmentally friendly, containing no harmful substances, aligning with global sustainability goals.

Technical Specifications: Precision Meets Performance
The PC-826 superplasticizer meets rigorous technical standards, ensuring consistent quality and reliability. Below is a detailed specification table:
| Order Number | Monitoring Project | Qualification |
|---|---|---|
| 1 | Appearance and color | White powder |
| 2 | Water content (%) | ≤5.0 |
| 3 | Effective content (%) | ≥95 |
| 4 | Density (g/L) | 500–700 |
| 5 | pH Value (10% aqueous solution, 20℃) | 6–8 |
| 6 | Chloride ion content (%) | ≤0.1 |
| 7 | Base content (%) | ≤3.0 |
| 8 | Water reduction (%) | ≥25 |
| 9 | Air content (%) | ≤6.0 |
