2019 Fiscal Year Research-status Report

Characterising and modelling the chloride resistance of blended-cement concrete by considering the effect of supplementary elements from glass

Research Project

Project/Area Number	19K15059
Research Institution	The University of Tokyo
Principal Investigator	王眺東京大学, 大学院工学系研究科(工学部), 特任助教 (70822386)
Project Period (FY)	2019-04-01 – 2021-03-31
Keywords	Glasses / SCMs / Chloride
Outline of Annual Research Achievements	1 Synthesizing works: Nine Glasses of various chemical compositions were synthesized in last year. Belite and Alite are also synthesizing in Beijing. 2 A paper "A study of the influence of crystal component on the reactivity of low-calcium fly ash in alkaline conditions based on SEM-EDS" has been published in Construction and Building Materials.
Current Status of Research Progress	Current Status of Research Progress 4: Progress in research has been delayed. Reason The synthesized works are delayed due to the COVID-19 since last year. The salt water immersion tests was also delayed since campus is closed.
Strategy for Future Research Activity	We are revising the experiment plans on synthesizing glass and cement considering COVID-19. The number and amount of glassed may be a little reduced. Other SCMs, like silica fume or metakaolin will be used to replace some of the glasses. The steady-diffusion test and salt water immersion test will be conducted immediately after the re-opening campus.
