Abstract
Práce se zabývá výzkumem vlivu mikrosférických aditiv na vlastnosti geopolymerních materiálů. Tato aditiva se používají do směsí pro účel 3D tisku. Byla zpracována rešerše v oblastech kompozitních a geopolymerních materiálů, surovin pro geopolymery a 3D tisk geopolymerů. V experimentální části jsou popsány jednotlivé použité experimentální metody (zkouška pevnosti v tlaku, zkouška ohybem, SEM, XRD, XRF, TGA, ztráta žíháním a distribuce velikosti částic), použité přístroje a materiály. Popsána je také metodika experimentů včetně přípravy vzorků a zkoušek. Do směsi byly přidávány keramické a skleněné mikrosféry v systematických řadách. Část připravených vzorků zůstala při laboratorní teplotě a zbytek byl temperován 1 h na teplotu 600 °C, 800 °C a 1000 °C. Měřena byla pevnost v tlaku a pevnost ohybem. U vzorků s 0,8 % aditiva byla také měřena pevnost v tlaku při teplotě 800 °C.
The work deals with the research of the influence of microsphere additives on the properties of geopolymer materials. These additives are used in mixtures for the purpose of 3D printing. A search was carried out in the areas of composite and geopolymer materials, raw materials for geopolymers and 3D printing of geopolymers. The experimental part describes the individual experimental methods used (compressive strength test, bending test, SEM, XRD, XRF, TGA, loss on ignition and particle size distribution), the instruments and materials used. The methodology of the experiments, including sample preparation and testing, is also described. Ceramic and glass microspheres were added to the mixture in systematic rows. Part of the prepared samples remained at laboratory temperature and the rest was tempered for 1 h at 600 °C, 800 °C and 1000 °C. Compressive strength and bending strength were measured. For samples with 0.8 % additive, the compressive strength at 800 °C was also measured.
