Abstract:
Reports data from a comparative, long-term study of several blended cements. The study compared the performances of five different binder systems for strength and for properties related to durability. It was found that both ground granulated blast furnace slag (ggbs/slag) and silica fume (microsilica) were very efficient in improving durability and impermeability. The two materials combined with OPC in a triple blend showed better performance than either on its own, and in this combination, silica fume compensated for much of the delayed strength development in slag cement concretes. Paper gives a thorough summary of the results obtained during the first 30 months of the project.
