Effect of Some Admixtures on the Surface Properties of the Hydration Products of Silica Fume/Ca(OH) Mixtures
Published 2000-04-01“…In addition, the interaction of such admixtures with the calcium silicate hydrates formed was investigated by infrared (IR) spectroscopic analysis. It was observed that both admixtures increased the specific surface area of the calcium silicate hydrates quite considerably relative to the behaviour of a blank sample (i.e. without addition of admixture), especially during the initial stages of hydration (after 24 h). …”
