Abstract
The object of the study was the influence of chemically modified silica fume (MSF) on the sulfate resistance of cement-based materials. MSF is a liquid product prepared from a suspension of silica fume and a water solution of a reactant under the defined composition of suspension, defined ambient temperature and time of procedure. MSF is added into mortar or concrete mixtures instead of water in the quantities needed for the desired consistency. The results obtained at the application of MSF shows a significant increase of sulfate resistance of materials based on Portland cement slag blends and slag binder. This positive effect represents a further ...
