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.enheat of hydrationfly ashsilica fumeslagconcrete
