The hydration of portland cement in presence of citric acid has been investigated. The results indicate that O.l% citric acid accelerates whereas too high a dose (> 0.1%) of citric acid retards the hydration. Electrical conductivity measurements of the paste indicate that in the presence of citric a
An optical interference method shows that at early stages of hydration there is a significant increase in size of individual cement grains. The effect of applied hydrostatic pressure on cement pastes is an increase in the degree of hydration. Explanations for these effects are given in terms of the
Conduction calorimetry has been used to study the patterns of early heat evolution during the hydration of Portland cement. In particular, the effect of sulphate on the rate of heat liberation has been investigated with reference to the differences observed depending on whether the sulphate is prese
