There is a possibility to generalize the procedure and to include the transfer of radiative and convective heat transfers. This represents a complex ab initio computation. The radiative and convective heat transfers may be coupled and a system of transcendent equations may be formed. Such a system may be solved e.g. by the Newton iterative method.

This special type of insulation finds its place in selected fragments of buildings. The subject is the study of transport phenomena of heat propagation through the structure of thermoreflective insulators, their physical properties and comparison with classical insulators. The topic includes the verification of structural thermal insulation systems both in the laboratory in the measuring cabinet and also during installation in buildings.

2. Application of the sol-gel method for the production of thermally insulating refractories

   One of the modern directions for obtaining high-quality refractory products is the application of the sol-gel method. The gelation process produces a spatial network that can be used as a lightweight binder in thermal insulation materials. Sol-gel technology brings with it a number of advantages. Compared to hydraulic bonding, the amount of water required for the preparation of the working mass is reduced and the subsequent drying rate can be increased without disturbing the dried material. Chemically pure colloidal solutions are used as a binder, which reduces the amount of unwanted oxides in the material and increases its refractoriness. Another advantage is the formation of new minerals, especially mullite, during firing. This thesis will deal with the design and study of sol-gel bonding for a lightweight refractory material.

3. Definition of optimal conditions of brick body creation to improve its useful properties and reduce environmental and energy intensity.

   Calcareous (carbonate) brick clays are the predominant basic raw material for brick production. By finding the optimal firing conditions of brick clays (depending on their chemical and mineralogical composition) it is possible to achieve the maximum positive effect of fired body hydration, which can be manifested mainly by increasing in strength, sound reduction index, frost resistance and reducing its water permeability. It is also necessary to define the hydration conditions (time, temperature).

5. Development of environmentally friendly masonry unites for modern building structures

   Tutor: Zach Jiří, prof. Ing., Ph.D.

6. Durability of geometric structures created by 3DCP technology depending on the material

   The research will focus on the study of the behavior of elements mmanufactured from cement composites using 3D printing technology. The influence of the composition of the mixture on the properties of the fresh mixture, the course of the hydration process of the cement and the final product will be monitored.

Accelerated degradation tests (exposure to liquid and gaseous aggressive environments, etc.) will be used to study durability.

   Tutor: Žižková Nikol, doc. Ing., Ph.D.

7. Influence of water-soluble hydrophobizations on the properties of cement composites

   The aim of the work will be to study the interaction of new water-soluble hydrophobizations with the surface of cement composites and an improvement of their durability, chemical resistance, and selected physical and mechanical parameters. The depth of hydrophobization penetration, change of microstructure of the surface layers of treated composites, positive effect on shrinkage of composites, etc. will be monitored. Hydrophobization will be assessed depending on dynamic viscosity, polymer base and method of application. It will also be monitored whether chemical reactions is occurred between the hydration products of the cement matrix and the hydrophobization. CT tomography will be used as a support for monitoring the change in the internal structure of hydrophobized surface layers of cement composites. The dependence of the hydrophobization's penetration depth on the type of elements with a cement matrix will also be observed, i.e. cement-bonded particleboard, various types of concrete, etc. The influence of nanoparticles on the possible improvement of the properties of water-soluble hydrophobization will also be investigated. The long-term durability and the possibility of applying additional layers of secondary protection will be examined.

8. Novel admixtures designed for alkali-activated materials

   The aim of the topic of the dissertation is the development of noval organic additives for alkali-activated materials. Existing admixtures used in concrete have either no or little effect on the technological properties of alkali-activated materials. Following the application of new technologies, such as 3D printing, and for a wider use of these materials in practice, it is necessary to develop new modifying admixtures. The main part of the work will be devoted to the influence of admixtures on the rheological properties of fresh pastes and the study of the principle of their action. Furthermore, the influence on the microstructure of the binder and the mechanical properties will be determined.

10. Study of the electrically conductive silicate composite system properties for heated outdoor surfaces

    The essence of the dissertation thesis will be composition of a system of silicate based electrically conductive materials with increased electrical and thermal conductivity, which will enable the realization of heated surfaces in the conditions of outdoor exposure. The whole system will be able to regulate the surface temperature through an autonomous system. The dissertation will also propose a technology to accelerate the hydration of fresh silicate composite, which will be achieved by heating the individual components of the composite system already in a fresh state shortly after application. This will prevent slowing down or stopping of the cement matrix hydration due to low ambient temperatures and will expand the range of outdoor conditions for the application of the entire system.
