Influence of humidity changes to properties of building materials with organic filler
 Vasas, Silvestr ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The bachelor's thesis deals with the issue of dimensional changes of building materials containing organic filler, in connection with changes in the humidity of the environment in which the material is located. Searches of knowledge, especially from the scientific literature showed a significant effect of moisture on volume and weight changes of both wood itself and wood of cement composites. In this respect, the treatment of wood (thermal, chemical, etc.) ort he surface treatment of the final wood of the cement composite (coating systém, impregnation, etc.) is essential to reduce the rate of change due to ambient humidity. Experimental laboratory assessment of dimensional and mass changes proved compliance with theoretical knowledge and extended them by specifying the effect on individual dimensions. The different behavior of cement-bonded particleboards in terms of their hygroskopicity was demonstrated on the changes of the boards surface threatment with the coating system and on the boards without surface threatment.
