The effects of supplementary cementing materials in modifying the heat of hydration of concrete

摘要

Supplementary cementing materials, such as ground granulated blastfurnace slag(GGBS), fly ash (FA) and condensed silica fume (CSF), are now routinely used in structural concrete. Used judiciously, these materials are able to provide improvements in the economy, microstructure of cement paste as well as the engineering properties and durability of concrete. They also alter the rate of hydration and can influence the time-temperature profile in large concrete elements.
