Blended binder systems in concrete have been in use for many years.However, over the recent discussions on the sustainability of cement and concrete the topic became of paramount importance for the construction industry.In Sweden blended binder systems in concrete were applied fairly recently and supplementary cementitious materials (SCM) were not used largely before.In Sweden over the last 30 years engineering structures were built, with exceptions, with a low alkali, sulfate resistant Portland cement due to domestic requirements.Therefore, in context to blended binder systems durability is a major point being discussed.Most interest lays in the resistance towards frost, carbonation and chloride penetration and the experience with blended systems was limited.
