Inorganic wastes like raw material for geopolymer binders
Hanzlíček, Tomáš; Perná, Ivana
2010 - Czech
Great amount of industry wastes lead to the technology which are able to use waste materials as additives to different types of matter or convert industry waste materials to the new basic material. Velké množství průmyslových odpadů vede k rozvoji technologií, které jsou schopné buď odpady využít jako plniva do jiných hmot, nebo mohou průmyslové odpady přímo konvertovat na nový základní materiál.

Examples of influence of structural conditions on landslide development in Beskydy and Vsetínské vrchy Mountains
Rybář, Jan; Klimeš, Jan
2009 - Czech
The influence of structural conditions on slope stability in the Western Carpathians flysh region was described and assessed using results of systematic engineering-geological mapping. S využitím výsledků systematického inženýrskogeologického mapování svahových deformací v měřítku 1 : 10 000 je na vybraných příkladech analyzován vliv strukturně geologických poměrů na stabilitu svahů v regiónu flyše Západních Karpat.

The use and disposal of the cinders from wooden masses and bio-wastes combustion
Hanzlíček, Tomáš; Perná, Ivana
2009 - Czech
The results of the 2009 year were focused on knowledge showing and proving that the bio-cinders do not contain the toxic or dangerous elements. Their composition of calcium and potassium salts predestinates the ashes as fertilizers. The composition of offered fertilizer was protected by patent proposal. Výstupem práce v roce 2009 je návrh na využití v rámci poznání, že popely neobsahují žádné toxické látky a naopak jejich obsah vápníku a draslíku je předurčuje k výrobě organicko-minerálního hnojiva. Jeho kompozice a způsob výroby je chráněn podaným průmyslovým vzorem a návrhem na udělení patentu.

Developments strenght attained of the system metakaolinite – podium aluminite - quartz
Hájek, Pavel; Koloušek, D.; Andertová, J.
2009 - Czech
/: Geopolymer reactions have much in common with diagenetic transformations of the sedimentary rocks. Inside of laboratory conditions occur of geopolymer masses in alkali reaction of metakaolinite to sodium aluminate (Fastex 81) and quartz. As a result reaction is rise the zeolite phase (zeolite A) inside of relevant substance. The zeolite phase, temperature dressing materials and hydrothermal exposition influence developments strength. Results reaction were confirmed by means of X – ray diffractometry and SEM. Geopolymerní reakce mají mnoho společného s diagenetickými přeměnami sedimentárních hornin. V laboratorních podmínkách vznikají geopolymerní hmoty při alkalické reakci metakaolinitu a hlinitanu sodného (Fastex 81) a křemene. Jako výsledek reakce je objevení zeolitové fáze (zeolit A) v dané hmotě. Zeolitová fáze, tepelná úprava materiálu a hydrotermální expozice ovlivňuje trendy pevnosti. Výsledky reakce byli potvrzeny pomocí XRD a SEM.

High pressure adsorption of HCI from gaseous mixture on artificial sorbent materials
Machač, P.; Balíček, P.; Bradáčová, K.; Koza, V.; Přibyl, Oldřich
2009 - Czech
High temperature adsorption of HCl was applied on simulated generator gas.The artificial sorption materials were based on CaO-Al2O3. Vysokoteplotní adsorpce HCl byla aplikována na modelovém plynu, který simuloval generátorový plyn vyráběný ze spalin dřeva. Pro adsorpci byly použíty uměle připravené sorbenty na bázi CaO-Al2O3.

Grant project solving and final summarization, Registration number of project: 102/07/0794, Name of project: Sensor of Rotational Movement around Vertical Axis for Seismology
Štrunc, Jaroslav
2009 - Czech
Within this project were developed prototypes of the seismic rotation motion based on the two principles and also a generator of rotational motion that can be used for seismic prospection. During the theoretical works and experiments we found that generator and sensor of rotational motion can be used in geophysical prospecting. V rámci tohoto projektu se podařilo jednak zkonstruovat a otestovat rotační senzory na dvou principech a dále připravit generátor rotačních kmitů pro testování a seismickou prospekci. Během teoretických analýz a praktických testů jsme objevili možnost použití rotačních vln jako prospekční metody.

Organic compounds in hardcoal waste piles studied by GC/MS and Py-GC/MS
Havelcová, Martina; Sýkorová, Ivana; Klika, Z.; Trejtnarová, Hana; Fojtíková, M.
2009 - Czech
GC/MS and Py-GC/MS techniques were used to provide information on set of samples from three waste piles localities in Czech Republic. Substituted and unsubstituted phenantrenes and other polycyclic aromatic hydrocarbons were comprised in sample extracts. The results were correlated with petrographic composition. GC/MS a Py-GC/MS techniky byly použity pro studium sady vzorků z uhelných odvalů ze tří lokalit České republiky. V extraktech ze vzorků byly nalezeny hlavně substituované a nesubstituované fenantreny a další polyaromatické uhlovodíky. Výsledky byly korelovány s petrografickou analýzou .

Bruthans, J.; Schweigstillová, Jana
2009 - Czech
The study describes chemistry and isotopic composition of water from unsaturated zone of sandstone. Studied waters are extremely acidified. Isotopic composition of H and O of studied waters lies at local line of meteoric water. Hlavním cílem této práce bylo popsat chemizmus a isotopického složení vody nenasycené zóny pískovců. Studované vody jsou extrémně acidifikované. Izotopové složení H a O studovaných vod leží na lokální linii meteorické vody.
