The Combustion of Organic Lightweighting Agents in the Chamotte Materials
Smékalová, Veronika ; Keršner, Štěpán (referee) ; Sokolář, Radomír (advisor)
Lightweight chamotte products are popular building material. There are many types of lightweight chamotte on the market, but the most popular lightening options are organic ingredients. This brings some problems to the production of these products. This thesis deals with the burning of various types of lighters from shards of fireclay materials. In the theoretical part are summarized raw materials, which are necessary for production of lightweight chamotte. The results of the published research studies on the topic of lightening of organic lightening products are being described here. The practical part deals with properties of products made of clay or kaolin with the addition of a certain amount of lighter. These added lighters are spruce sawdust, beech sawdust, peat, bran, paper slurry and anthracite. All these lighters are direct. For comparison, the cenospheres, which represent indirect lightweights, were also included in the research. For all specimens, the temperature interval of burnout of specimens, refractoriness, classification temperature, bulk density, thermal conductivity coefficient and other properties were defined.

History of anthracite and lignite mining in České Budějovice region compared from a point of view of economic and social history
PETRÁŠEK, Karel
The bachelor's thesis focuses on the historical development of coal industry in Českobudějovicko region during the first half of 20th century. The work is divided into three parts. In the first part, the author focuses on the creating of coal deposits in Czech lands with usage of the available literature. he also describes South Bohemian deposits and quality of local kinds of coal: anthracite and lignite. The second part deals with the development of Czech coal industry. The work focuses on South Bohemian coal mining industry until the end of 19th century. The last part is dedicated to the history of three mining locations where coal was mined during the first half of 20th century. These locations are Kamenný Újezd, Mydlovary and Lhotice. While dealing with these locations the thesis focuses on local mines' history, analyzes the problems they struggled with and social conditions of their employees. The results are then compared with situation in other Czech coal mining regions.
