Multi-chemo-physical approach to performance assessment of structural concrete with SCMs

le 15 novembre 2018
à 13h30

Tetsuya Ishida, Professeur au Département Génie Civil de l'Université de Tokyo (Japon), interviendra lors d'un séminaire.

The use of supplementary cementitious materials (SCMs) to improve concrete performance has increased around the world in recent decades. Engineering practices demand a unified model for SCMs to predict and optimise the performance of blended-cement concrete.  A Finite Element Numerical Model DuCOM-COM3, developed at the Concrete Laboratory, the University of Tokyo, is a multi-chemo-physical and multiscale analysis platform that can trace the whole-life behaviour and performance of reinforced concrete structures. However, the intrinsic heterogeneity and variability of SCMs present great challenges to the modelling of blended-cement concrete. This presentation first reviews the challenges and difficulties of current models of blended-cement concrete. A multiphase modelling scheme based on DuCOM-COM3 analysis platform is introduced to consider different SCMs. Using the modelling scheme, a research road map for blended-cement concrete modelling is introduced for future study.
