How does silica fume change cement slurry, mortar and

Silica fume is a highly reactive pozzolan. In hydrating cement paste, silica fume will react with CH to form calcium-silicate hydrate (CSH). silica fume contacts mixing water and forms a silica-rich gel, absorbing most of the available water. This gel then agglomerates between the grains of unhydrated cement, coating the grains in the process.
