Development of a simplified nondestructive method for in-situ evaluation of the cover concrete quality and durability design.

我已经进行了一些初步的实验室实验，以确定测量温度对WIST结果的影响。具体而言，将一些可用的样本保存在环境室中，以便在四种不同温度（即5、20、30和35 °C）下进行WIST测量。一些研究结果发表在《建筑和建筑材料》杂志上。此外，还制备了各种混凝土试件用于其他实验测量。在放入环境室之前，在房间中对样本进行处理并干燥至适当水平。测量温度和相对湿度对WIST结果的影响已经为2023财年的批量实验做好了准备。制备了不同温度和相对湿度的原位测量条件。

I have conducted some preliminary laboratory experiments to determine the impact of measurement temperature on WIST results. Specifically, some of the available specimens were preserved in an environmental chamber in order to conduct WIST measurements at four different temperatures (i.e. 5, 20, 30, and 35 °C). Some of the findings were published in the Construction and Building Materials journal. In addition, various concrete specimens were prepared for other experimental measurements. Before being placed in the environmental chamber, the specimens were processed and dried to the proper level in a room. The influence of measurement temperatures and relative humidities on the WIST results has been prepared for bulk experiments in the fiscal year 2023. Some in-situ measurement conditions with different temperatures and relative humidities were prepared.
