Characterization of Sealants and Adhesives Behaviour as Fulfillments of Cracks in Wood
 Laciková, Petra ; Běťák, Adam
The primary aim of this research is to assess the durability of available adhesives and sealants, intended for rehabilitating oversized cracks in wood structures. Spruce wood was used as filling material to prepare surface-glued samples. The highest compressive shear strength values were observed for reference samples (without exposure stress) bonded with adhesives. The achieved shear strength values for the epoxy and polyurethane adhesives were 80% higher than for the sealants. The adhesion failure was visually assessed. The effect of the filler on the tensile properties was assessed for the epoxy adhesive.

Bio-based adhesives for wood structures
 Laciková, Petra ; Rovnaník, Pavel (referee) ; Vaněrek, Jan (advisor)
This thesis deals with adhesives designed for wooden structures. It focuses on adhesives with zero or minimal emission of formaldehyde, its replacement by more environmentally friendly substances based on tannins and lignins. The study is concerned with the characteristics of the most frequently used wooden structural elements, knowledge about traditional adhesives and research analysis of the so far developing "green" adhesives. Theoretically, it determines the selection of the most suitable type of filler influencing the properties of the adhesive based on the performed optimization process.
