Influence of Hydration Heat of Fly Ash Concrete on Size Effect

Abstract:

In this paper, the influence of fly ash concretes sustained hydration heat release effect on strength size effect was studied, by using different curing temperature indoor and outdoor in winter. The results showed that the reduce of hydration heat for fly ash concrete is not conducive to ensure the strength of concrete cured outdoor or indoor in winter. However, the growth of volume is beneficial to ensure the necessary hydration heat in concrete curing, so that the size effect of concrete strength appears that the strength increases with size increasing.
