| Description
| - New possibilities opened up by synchrotron radiation present x-ray tomography as an experimental imaging method to study the microstructural evolution during cement hydration. The present work demonstrates the potential of synchrotron-radiation microtomography for the investigation of cement structure after solidification. Quantitative determination of the spatial absorption- coefficient distribution due to the use of monochromatic radiation and the achieved high spatial resolution allows us to characterise the hydration process of cement volume on a micrometre scale in three dimensions. In particular, effects as the formation of microcracks and pores related to autogeneous shrinkage involved with the hydration process could be observed for the first time with down to one micrometre resolution.

- Nové možnosti, které skýtá synchrotronové záření, činí z rentgenové tomografie metodu experimentálního zobrazování, která je vhodná pro studium vývoje mikrostruktury při hydrataci cementu. Práce ukazuje potenciál synchrotronové radiační mikrotomografie pro výzkum struktury cementu po tuhnutí. Kvantitativní stanovení rozdělení koeficientu prostorové absorpce použitím monochromatického záření a dosažené vysoké prostorové rozlišení umožňují charakterizovat hydratační proces objemu cementu na mikrometrické stupnici ve třech rozměrech. Zvláště takové účinky, jako tvorba mikrotrhlin a pórů, spojené se samovolným smršťováním při procesu hydratace, lze poprvé pozorovat s rozlišením pod jeden mikrometr. (cs)
