Mechanical and physical tests on lime mortars with metakaolin and their suitability for repair of protected historic monuments
Válek, Jan ; Slížková, Zuzana ; Zeman, Antonín
Mechanical and physical tests on lime mortars with addition of metakaolin from new sources in the Czech Republic were carried out in the laboratories of the Institute of Theoretical and Applied Mechanics AV CR during 2004 to 2006. The tests results were used for design of optimised calcining temperature of kaolin, proportion of gauging between lime and metakaolin, and evaluation of influence of addition of Portland cement. Discussion of the results includes suitability of metakaolin gauged lime mortars for repair of historic monuments.

Dynamics of Earth gases emissions in Czechia
Kroufek, J. ; Stejskal, M. ; Šebor, G. ; Mrlina, Jan ; Tesař, J. ; Suchý, V. ; Zeman, A.
A monitoring of the Earth gases emissions was carried out at selected sites in Cechia. Particularly, methan, CO2, SO2, Rn a H2S were investigated. It was proved that neither the chemical composition, nor the emissions themselves can be considered as permanent. They may be affected by geological processes including earthquakes, as well as by man-made activities.
