The Porous Network and its Interface inside Geopolymers as a Function of Alkali Cation and Aging

Popis výsledku v původním jazyce

A combination of powerful characterization techniques was used to make a thorough description of solid geopolymers and of the associated effect of varying the alkali cation source and aging for up to several years. The local and pore structures were determined from atomic local scale up to several nanometers by pair distribution function analysis, small-angle X-ray scattering, and longer correlation concerning the pore network, and possible diffusion and accumulation phenomena were unraveled by thermoporosimetry and electrochemical impedance spectroscopy. These complementary observations resulted in a picture of an interface between the mineral and the porous network that was correlated to the solvated alkali cation present in the porous solution. After a short time of a few months, the Na-based geopolymer was found to exhibit a smooth interface. This contrasted with the K- and Cs-based geopolymers, which presented developed interfaces arising from hierarchically organized smooth parti
