Abstract
This paper reviews the chemical admixtures preventing delayed ettringite formation (DEF) and
can be used for researchers to (i) identify potential chemicals alternative to the conventional methods using
supplementary cementing materials (SCMs) and evaluate these chemical solutions to prevent DEF via reported
mechanisms, (ii) understand the effects of these chemicals on the concrete properties, and (iii) develop
guidelines and/or implementation plan for future research
