Apartment building
Sedlačík, Martin ; Průša, David (referee) ; Brukner, Bohuslav (advisor)
The goal of bachelor thesis is to design and develop project documentation for a new apartment building with almost zero energy consumption for construction. The apartment building is located in Sady part of the town Uherské Hradiště. It is a five-storey building with an underground garage. A total of 14 apartments with balconies with a view on a part of Uherské Hradiště are designed in the building. The bearing masonry will be made up of cut clay brick blocks on which cast-in-place reinforced concrete floor will be placed. The building will be insulated with ETICS system. Facade colors will be in shades of gray and blue. The building will have an elevator and reinforced concrete staircase.
Magnetic properties of electrospun polyvinyl butyral/Fe2O3 nanofibrous membranes
Peer, Petra ; Cvek, M. ; Urbánek, M. ; Sedlačík, M.
In this contribution, magnetic Fe2O3 nanoparticles (MNPs) were successfully incorporated into the polyvinyl butyral (PVB) nanofibrous membranes using the electrospinning process. The effects of the MNP concentration on the morphology of the nanofibres and their magnetic properties were investigated. Scanning electron microscopy and transmission electron microscopy confirmed their concentration-dependent, yet uniform diameter, and the presence of well-embedded MNPs inside the PVB nanofibres. The magnetic properties of the PVB/MNP membranes were studied using the vibrating-sample magnetometry. The saturation magnetization increased from 6.4 to 45.5 emu/g as the MNP concentration in the feedstock solution increased from 1 to 15 wt%. The fabricated PVB/MNP nanofibrous membranes possessed the ability to respond to the external magnetic fields, which determines their potential in the development of the advanced smart textiles.
Inorganic thermal insulation material for masonry elements
Sedlačík, Martin ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
This master’s thesis deals with preparation of foam glass and explores the possibilies of utilization of this material as an inorganic thermal insulating filler of fired hollow bricks. Foam glass was prepared via powder sintering method from waste packaging glass, using limestone and graphite as foaming agents. After inital analysis of raw materials, the effect of mixture composition and different processing parameters on bulk density, pore size and morphology of foam glass was investigated. Last but not least, different ways of manufacturing thermal insulating bricks, by preparation of foam glass directly in the cavities of fired hollow bricks, were tested.
Possibilities of utilisation of salt slags from aluminum production
Sedlačík, Martin ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
Bachelor thesis deals with characterisation of salt slag formed during melting of aluminium scrap in rotary furnaces and proposes options of utilization of this material as a secondary raw material. Samples from top, middle and bottom part of mould, where slag cools down after the melting process is finished, were tested. Aim of the thesis is also to evaluate the effect of air access during the cooling process on phase and chemical composition of salt slag. Particle size distribution, content of soluble substances and composition were examined in collected samples. Phase and chemical compositions of both soluble and insoluble portion of idividual fractions were determined using X-ray powder diffraction and X-ray fluorescence spectrometry.
