Activation of Portland cement blended with high volume of fly ash using Na2SO4
TL;DR: In this paper, the effect of sodium sulphate (Na2SO4) on the activation of Portland cement blended with 50wt-% class F fly ash was studied and the results indicated that mortar workability was improved.
Journal ArticleDOI
Carbonation curing of cement mortars incorporating carbonated fly ash for performance improvement and CO2 sequestration
TL;DR: In this paper, the authors investigated the performance of cement mortar incorporating carbonated fly ash (FA) and the synergistic effect with carbonation curing and showed that the content of free CaO and the hydration heat were reduced apparently by carbonation treatment.

Hydration of Portland cement with high replacement by siliceous fly ash
Florian Deschner,Frank Winnefeld,Barbara Lothenbach,Sebastian Seufert,Peter Schwesig,S. Dittrich,Friedlinde Goetz-Neunhoeffer,Jürgen Neubauer +7 more
TL;DR: In this article, the effects of fly ash on the hydration of ordinary Portland cement pastes were investigated over a hydration time of 550 days and the results were compared with a reference blend of OPC containing 50% of inert quartz powder allowing the distinction between "filler effect" and pozzolanic reaction.

Methods for determination of degree of reaction of slag in blended cement pastes
TL;DR: In this article, the degree of reaction of slag in blended pastes is measured using a combination of Selective dissolution and differential scanning calorimetry, but the absolute heat of hydration or contribution to chemical shrinkage of any particular slag is not known.
