| 研究実績の概要 |
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.

2: おおむね順調に進展している
理由
Based on careful preparations, the project is running rather smoothly.
|
| 今後の研究の推進方策 |
The impact of relative humidity, rain, sun radiation, wind, and their combinations on the WIST results is being investigated concurrently using comparable methodologies. Some obtained results will be continue analyzed for publishing in ISI journals and conferences.
|
| 次年度使用額が生じた理由 |
Analysis of the obtained results has taken longer time than estimated plans. This leads to some publications (ISI Journals and conferences) have not finished in the fiscal year 2022 and moved to the fiscal year 2023. As a result, the budget has not been used as the original estimation.
The remaining budget will be used for long-term experimental measurements, publication fees, transportation expenses, and accommodation expenses for in-situ measurement in the fiscal year 2023.
