Modification of the composition of cement composites containing organic fillers via alternative raw materials
 Janek, Ondřej ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
Nowadays the construction industry consumes predominantly non-renewable raw materials. To achieve long-term and sustainable development is necessary to start using renewable sources. This bachelor thesis deals with the possibilities of using alternative renewable raw materials. Additionally, an overview of current developments cementitious composites with organic fillers is presented. Based on the study of research papers is summarized possibility of partial or complete substitution of filler or binder.

Boards with alkali activated binder filled with wood chips
 Gajdušková, Patricie ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
For the production of cement chipboards, cement is used as a binder which is an ecological burden for our planet. This diploma thesis deals with research into the possibility of replacing it with other alternative materials, especially those that are created as a by-product of other production. The focus is primarily on slag, heating plant slag or brick dust. The theoretical part deals with the previous studies and theoretical knowledge of alkaline-activated matrices which are supplemented with an organic binder such as wood chips which are used to reinforce the boards. The practical part deals with the above-mentioned alternative materials which are tested for the design of recipes for modified boards made of alkali-activated binder reinforced with chips. These modified recipes are subsequently subjected to physical-mechanical tests such as bending strength, modulus of elasticity and other monitored parameters of the boards. Selected board variants were analysed in terms of mineralogical composition and microstructure.
