Strength and Microstructural Characteristics of Activated Fly Ash
The hydration process in the fly ash–cement system initiates with the hydration of clinker minerals, followed by a secondary hydration reaction between Ca(OH) 2 and FA. The surface of FA adsorbs and reacts with Ca(OH) 2 produced during the hydration of cement clinker, leading to the formation of C-A-H and C-S-H. In the presence of gypsum and ...
