Abstract
Diplomová práce se zabývá analýzou nového materiálu, kterým je geopolymer. Tento materiál má veliký ekologický význam při výrobě, a to že nevznikají žádné emise. Dále se zkoumá nanovlákenná membrána z hlediska její propustnosti při zátěži vodním sloupcem. Nanovlákenná membrána je zkoumána samostatně a ve spojení s geopolymerem. Geopolymer je testován s nanovlákennou membránou zabudovanou uvnitř, ale také jako samostatný materiál. Dále se zkoumá geopolymer s příměsí hliníku s určitým procentem. Maximálně se přidává 1 %, takto vysoké množství způsobuje v materiálu póry. Při experimentech se testuje geopolymer s příměsí hliníku 0,5 % a 1 %. Také byl vytvořen experiment s různými procenty hliníku v geopolymeru a byl sledován jejich růst při určitém procentu. Dále jsou v práci popsány chyby způsobené při měření, ale i při výrobě geopolymeru. Způsobené póry způsobují vyšší nasákavost než v původním geopolymeru bez příměsi hliníku. Geopolymer s membránou byl zkoumán také mikroskopicky, a to z hlediska zda geopolymer nenarušuje nanovlákennou membránu. Tato práce je především zaměřená na analýzu geopolymeru a jeho vlastností.
The diploma thesis deals with analysis of new material, which is a geopolymer. This material have of great ecological importance in production, and it that doesn't produce any emissions. Further, the nanofiber membrane is examined in terms of its permeability at the water column load. The nanofiber membrane is investigated separately and in conjunction with the geopolymer. Geopolymer is tested with a nanofiber membrane inside, but also as a separate material. Further, a geopolymer with an admixture of aluminum with a certain percentage is examined. At most 1 % is added, so high amounts is makes in the material of the pores. In the experiments, a geopolymer with an admixture of aluminum of 0.5% and 1% is tested. Also was created experiment with different percentages of aluminum in the geopolymer and their growth at a certain percentage was monitored. Furthermore, errors in the measurement are described, but also in the production of geopolymer. Caused pores cause higher water absorption than in the original geopolymer without an aluminum admixture. The geopolymer with membrane was also examined microscopically, in terms of whether the geopolymer didn´t interfere with the nanofiber membrane. This thesis is primarily focused on the analysis of geopolymer and his properties.
