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.
