	abstract = {Rigid PVC wood flour composites were prepared with various volume fractions of wood flour to investigate the effect of the structure properties on the fractural and tensile behavior. During the mixture preparation the first question is the compatibility of the wood flour additive with the rigid PVC and the safe concentration range of the additive. The second question is the fractural behavior of the composites. Accordingly, the 300–400 micrometer particle size beech wood content was varied using 15, 20, 25 parts per weight of the polymer matrix. Since both the PVC and the major components of the beech wood (cellulose and lignin) are polar, we did not use a coupling agent between the polymer and the natural filler. Thus, the properties of the composites as function of concentration can be examined. The usual mechanical properties, such as tensile strength, elongation at break and so-called compact tensile fracture mechanical analysis was also performed. It has been found that the composites could be safely processed with up to 25 parts by weight wood content. However, the properties of 25 parts by weight filler content sample already showed a decrease in strength properties. We also tried to improve the fracture mechanical properties with fibrous (1 cm long) natural filler. In this case 20 parts by weight of wood flour content with one, three and five parts by weight hemp fiber were used in the PVC polymer matrix. The tests results showed that these fibrous fillers neither decrease nor improve the mechanical properties. The raw measurement results were evaluated according to the critical stress intensity factor (Kc) and the critical crack propagation energy (Gc). Ultrasound propagation measurements are in progress trying to determine the effect of structural changes and interactions at increased hemp fiber content.},

	abstract = {Ceramics reinforced with carbon and silicon carbide particles are of great importance in the field of technical ceramics and ceramic composites. In this research, the possibilities of producing advanced ceramics from traditional, relatively inexpensive materials were studied. The authors have successfully developed mullite ceramic materials reinforced with carbon particles using kaolinite powder and sawdust. Powder mixtures with different compositions were prepared in a planetary ball mill using silica balls. The produced mixtures were compacted in a 100 kN pull-press to produce pellets using a pressure of 140 MPa. The prepared specimens were sintered in a laboratory chamber kiln under oxygen deficient conditions at 1250°C. After sintering of the specimens, considerable amounts of carbon content were incorporated into the material structure of produced ceramics, which were confirmed by energy-dispersive X-ray analysis. Using 10–20 m% sawdust in the mixtures, the carbon (C) content of sintered specimens was found to be more than 8 m%.

	abstract = {Geopolymers are inorganic amorphous aluminosilicate materials, which can be produced by the alkali activation of materials with high aluminum and silicon content. In this research, we prepared geopolymer samples obtained from construction and demolition (C&D) waste materials (brick powder and concrete powder), as well as industrial waste material (aluminum dross), and we investigated them using different test methods. Density, particle size distribution and chemical elemental composition were determined on the dried powdered waste materials, and microstructural observations were also made using a scanning electron microscope (SEM) technique. To prepare the geopolymer sample mixtures of sodium-hydroxide and sodium silicate, we used an alkali activator solution at different concentrations (4 M, 8 M and 12 M). We used Fourier Transformation Infrared Spectroscopy (FTIR) to reveal new phases in geopolymer samples. Compression strength was determined after 7 days and after 28 days. In the cases when aluminum dross was used, a gas-forming reaction took place in the geopolymer pastes; therefore, foamed geopolymer was produced. According to these results, the used C&D and industrial wastes may be potential raw materials which could be used to prepare geopolymers.
