| Material research and development | Optimize the formula of concrete expansion agent and improve its performance |
| Engineering applications | Provide accurate expansion performance data support for engineering design and construction |
| Shrinkage-compensating concrete | Used to evaluate the expansion performance of shrinkage-compensating concrete to ensure that it can effectively compensate for shrinkage stress and prevent cracking. |
| Self-stressed concrete | Determine the expansion rate of self-stressed concrete to ensure that it can generate sufficient self-stress to meet engineering needs. |
| Massive concrete | Used to evaluate the expansion performance of large-volume concrete and prevent cracking caused by temperature changes. |
| Prefractory concrete | Determine the expansion rate of prestressed concrete to ensure that it can effectively apply prestress and improve structural stability. |
| Laboratory research | Used for the research and development and performance testing of concrete expansion agents to optimize material formulations. |
| Engineering site testing | Real-time monitoring of the actual effect of concrete expansion agents at the construction site to ensure project quality |
| High-precision measurement |
| Using high-precision displacement sensors and non-expansion alloy calibration rods, the measurement error is controlled within ±1μm, ensuring the accuracy and comparability of long-term test results. |
| Flexible testing and high turnover rate |
| Testing after reaching the age, no long-term online observation is required, which significantly improves the efficiency of equipment use. |
| Automated data management |
| The test process does not require manual recording, and all data is automatically stored in the test host. |
| Testers can export data through a USB flash drive and use Excel software to conveniently view and analyze. |
| Intelligent data recording |
| The test results are automatically accompanied by the operator's identification, and the test time, ambient temperature and humidity, specimen number, age and specimen length are recorded to ensure that the data is complete and traceable. |
| Security authority management |
| The equipment is equipped with an authority setting function, and non-operating personnel cannot log in, which effectively guarantees the security and confidentiality of the test results. |
