Kinetics and mechanism of reaction in the zeolitic tuff-CaO-H sub 2 O systems at increased temperature

Kinetics and reaction mechanisms in the title systems were studied at increased temp. (65 Degrees C) by XRD and SEM. These reactions yield macrokinetic images of consecutive diffusion-controlled topochemical reactions. The initial process consists of the diffusive dissolution of zeolite and portland...

Zusammenfassung:Kinetics and reaction mechanisms in the title systems were studied at increased temp. (65 Degrees C) by XRD and SEM. These reactions yield macrokinetic images of consecutive diffusion-controlled topochemical reactions. The initial process consists of the diffusive dissolution of zeolite and portlandite. The final product (tobermorite) is formed by heterogeneous nucleation on the solid (CSH(I))-liquid (solution) interface.
