Průzkum a hodnocení dřevěného krovu historické budovy / Exploration and evaluation of historic timber roof of the buildingČervený, Radek January 2012 (has links)
My dissertation is based on the appraisal of wooden roof construction in baroque church Nanebevzetí Panny Marie in Vranově nad Dyjí. The main reason of this appraisal was preserving the church´s interior which was newly reconstructed with high historical value. The dissertation includes also the rehabilitation solution. The appraisal was based on the research witch used sense and instrumental methods. In the first part were found out all size of each construction´s parts and was established the type of rafters´ systém. Then the research solved some impaired wooden parts and their reasons. For suitable rehabilitation solution was defined the transition between well and impaired part. The best rehabilitation solution is the construction solution by the conditions using further procedures, e.g. preventive chemical protection.

Vývoj speciálních sanačních hmot na beton pro extrémní namáhání s využitím druhotných surovin / DEVELOPMENT OF SPECIAL REHABILITATION MATERIALS FOR CONCRETE FOR EXTREME STRESS WITH USE OF SECONDARY RAW MATERIALSHodul, Jakub January 2019 (has links)
The doctoral thesis deals with finding the use of some waste and secondary raw materials in the production of special polymer remediation materials for concrete, which could be applied even in constructions, where extreme mechanical and chemical load is occurred. The aim of this doctoral thesis is experimental examination of the possibility of using selected types of waste, including hazardous waste which represent the highest risk to environment, and secondary raw materials as a substitute for the currently used primary fillers in order to reduce the ecological footprint of the product itself. Some types of secondary raw materials, such as filter fly ash contaminated by flue gas denitrification process, are no longer used as a concrete admixture or partial cement substitution due to unwanted release of toxic ammonia (NH3). Mainly for this reason, the thesis deals with the progressive utilization of such types of secondary raw materials as well as with another currently unused waste into polymeric patching, grouting and anchoring materials while preserving or improving the final properties compared to reference materials using only primary raw materials. The result of this thesis is to find out suitable formulations for efficient preparation of special polymeric remediation materials for concrete containing waste and secondary raw materials as fillers. The partial aim of the thesis and a the scientific contribution is an observation of the developed materials internal structure using a modern device, CT tomography, an influence of the filler type on the long-term durability, and last but not least the observation of the rate of pollutants incorporation, found in hazardous waste, into the polymeric matric with the aid of EDX and FTIR analysis.
