dc.description.abstract |
This paper reports on core temperature development and initial shrinkage of fly ash cement pastes activated with
sodium hydroxide solution at different concentrations during elevated-temperature curing at 60°C. The results indicate
that a high sodium hydroxide concentration might result in a substantial rise in the core temperature of samples,
dependent on the mould size and ratio of paste to oven volume. An increase in alkali concentration was also found to
increase the initial shrinkage of the pastes during elevated-temperature curing. Excessive initial shrinkage and
temperature increase might lead to the appearance of internal stresses in the pastes, which can affect the material
performance. |
