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

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.
