Lime Mortars Modified by Fine Ground Brick Body
Šmerdová, Ludmila ; Vyšvařil, Martin (referee) ; Rovnaníková, Pavla (advisor)
Natural pozzolanic materials played an important role in Ancient architecture. In the last decades and nowadays it is artifical pozzolan which especially finds its use as an additive to mortar and concrete to improve some, especially the mechanical properties. This master thesis deals with study of pozzolan type of fine brick powder which is a by-product of the production of calibrated bricks. Along with studying pozzolanic activity of brick powder, lime mortar with different proportions of brick powder as an additive or replacement of lime dust are investigated. What is observed is its impact on the consistency of these mortar, water absorption, strength in time or fracture-mechanical parameters of mortar. The results may indicate the possible potential use of this source of pozzolanic admixture in lime mortar and plaster which are nowadays mainly used for the restoration of facades of historic buildings.

Renovation of the castle in Velké Němčice
Malínková, Valerie ; Muroň, Ivo (referee) ; Ležatka, Lukáš (advisor)
This bachelor thesis deals with the restoration of a castle in Velké Němčice. The thesis builds on an architectural study carried out in the AG033 course of the Restoration of Monuments Studio. The task of the thesis is to create a complete project for the appropriate restoration and reconstruction of the castle and to propose its new utilization. At the same time, the thesis focuses on the solution of the castle's immediate surroundings. The object of the solution will be designed as a socially cultural object with administrative functions. The castle should serve as a new town hall, and in accordance with this, the following rooms will be created in the castle: a ceremonial hall, information center, mayor's office, secretary's office, registry office, accountant's office, archive, library, club room, refreshment facility, and interactive room. To achieve the implementation of the new operation in the castle, the correct restoration of the historical object is necessary. Using surveys and historical sources, I examine the architectural values and construction of the building. I strive to preserve historically significant layers, remove intrusive modern elements, and return the object its original expression. With the help of new technologies, I also strive to preserve the building for future generations. I propose minimum use of modern structures and elements, and therefore mainly focus on proper reconstruction and restoration.

Lime mortars with the addition of ground limestone
Žižlavský, Tomáš ; Rovnaníková, Pavla (referee) ; Vyšvařil, Martin (advisor)
The thesis is focused on an effect of addition of ground limestone on properties of lime based mortars. Theoretical part of the thesis deals with diferenciation of plasters and their utilization, history of using limestone as an aggregate, its exploitation in the present and its impact on properties of lime based plasters, specially on strenghts. In the next part there's elaborated the carbonation reaction including the influence of external agents. Practical part of the thesis is focused on proving assumtions from theoretical part, particulary on the influence of ground limestone on the strenght properties of lime based plasters.
