The 2020 Japan Society of Civil Engineers Thesis Award
June 25, 2021
The research team of Professor SAEKI Tatsuhiko and Associate Professor NAKAMURA Ryota of the Civil Engineering Program at the Faculty of Engineering received the 2020 Japan Society of Civil Engineers Thesis Award. The Japan Society of Civil Engineers Thesis Award is given to the authors of articles recognized as having significantly contributed to the progress and development of science and technology in civil engineering by publishing articles on research, planning, design, construction, devising and maintenance in the publications of the Japan Society of Civil Engineers with their original achievements.
Professor SAEKI was awarded the Japan Society of Civil Engineers Article Award for the second time, following his 2011 award.
Title of the award-winning article
"An Estimation Method for Surface Chloride Concentration on Concrete under Airborne Chloride Cenvironmen”
Journal carrying the article: JSCE Collection of Articles E2 (Material and Concrete Structure), Vol. 76, No. 2, pp. 98-108, 2020.
Award winners
SAEKI Tatsuhiko (Niigata University), TOMIYAMA Jun (University of the Ryukyus), NAKAMURA Fuminori (Nagaoka University of Technology), NAKAMURA Ryota (Niigata University), HANAOKA Daishin (Kanazawa Institute of Technology), Lin An (Kyoto University), SASAKI Iwao (Public Works Research Institute), ENDOH Hirotake (Civil Engineering Research Institute for Cold Region, PWRI)
Reason for the award
In this article, exposure tests were conducted at 101 locations throughout Japan. The amount of chloride ion permeation into the specimen was converted to the surface chloride ion concentration of concrete. By using the parameters considering the effects of altitude, wind direction and wave energy, they proposed an estimation formula that can accurately evaluate the surface chloride ion concentration regardless of the region. The results of this research are expected to greatly contribute to the rational durability design against salt damage and was recognized as suitable for the thesis award.
