Study of hydration mechanisms in the high alumina cement-sodium silicate system

Ding, J. / Fu, Y. / Beaudoin, J.J.

The retarding effect of sodium silicate on high alumina cement (HAC) hydration is demonstrated. The effect of sodium silicate addition on phase formation in HAC paste during hydration is studied. A reaction mechanism involving strätlingite formation in the HAC-sodium silicate system is postulated. Test results indicate that presence of silicate can strongly retard the hydration of high alumina cement. It promotes the formation of strätlingite.
