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.
