This communication explores the influence of boundary effects, embedded sensors and crack opening on high-temperature experiments of concrete as revealed by in situ neutron tomography. The hypotheses routinely taken about these experimental aspects in common practice are hereby reassessed in light of the insight given by noninvasive full-field measurements. Notably, we directly assess the heat and moisture insulation techniques and reveal the influence of temperature and gas pressure monitoring on the testing conditions, opening new perspectives toward their improvement.

混凝土高温实验测试条件的一些观察：中子断层扫描的见解

本次交流探讨了边界效应、嵌入式传感器和裂缝开口对原位中子断层扫描所揭示的混凝土高温实验的影响。根据无创全场测量提供的见解，特此重新评估在常规实践中对这些实验方面常规采取的假设。值得注意的是，我们直接评估了隔热和防潮技术，并揭示了温度和气压监测对测试条件的影响，为它们的改进开辟了新的视角。
