Introduction
In-depth interpretation of GB/T 43876—2024 Cement paste viscosity determination method
| Standard framework dimensions | GB/T 43876—2024 Characteristics | Scope of application | Technical requirements |
|---|---|---|---|
| Determination principle | Single-cylinder rotational viscometer, calculating shear stress and rate by measuring the deflection angle of the elastic element | Cement paste | Accurate to < strong>0.001 Pa·s |
| Instruments and equipment | Single-cylinder rotational viscometer, cement paste mixer, etc. | Laboratory environment control | Measurement error< strong>±5% |
| Sample preparation requirements | Water-cement ratio 0.50, cement dosage 600g ±2g | 3 groups of parallel tests | Arbitration water is grade 3 water |
Case analysis and practical application
In the actual inspection of a large cement plant, the single-cylinder rotational viscometer was used to determine the viscosity of cement paste in accordance with GB/T 43876-2024 standard. The results show that when the cement type is < strong>Portland cement, the average viscosity value is < strong>15.2 Pa·s, which is in line with the expected range.
