Utilizazion possibilities of bricks grinding waste in alkali activated systems
Dzurov, Matej ; Kalina, Lukáš (referee) ; Šoukal, František (advisor)
The bachelor’s thesis deals with usage of brick grinding waste, arising from the grinding process of modern bricks, as a constituent of alkali activated binders. The aim of the thesis is to verify the properties of brick grinding waste and to test mechanical properties of mixtures with different proportions of brick grinding waste and ground-granulated blast furnace slag, activated by commonly available hydroxides and combinations of hydroxides and water glasses. Furthermore, the effects of temperature increase on properties of prepared test samples were investigated and formation of carbonate effluent was observed.

SCC with secondary raw materials
Ťažká, Lucia ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
Bachelor thesis is focused on the possibility of using secondary raw materials and their application to the production of SCC. Large part deals with impurities of type I and its application results mainly from abroad. Furthermore, this work examines the impact of different types of impurities on the resulting concrete durability in various aggressive environments. The practical part is focused on the use of chemically non-reactive additives of type I instead of the commonly used additives of type II which are used to replace part of cement and the resulting design and manufacture of low-strength SCC using appropriate additives.
