This study aimed to reveal the petrography and physical-mechanical properties of limestones, which have an important reserve and are used as marble, in Tut district of Adıyaman province, which is one of the important cities of southeast Anatolia. As a result of petrographic analysis of the rock known commercially as Emprador, it was determined that it is bioclastic limestone with abundant nummulite fossils. Density, dry and saturated unit weight, water absorption, surface roughness, abrasion resistance and uniaxial compressive strength tests were applied to determine the physical and mechanical properties of the limestones. According to the test results obtained, the density of the limestones, dry unit weight, saturated unit weight, water absorption by weight, water absorption by volume, average surface roughness, ten points roughness average, maximum roughness value, Bohme abrasion resistance and uniaxial compressive strength values were determined as 2.486 gr/cm3, 2.478 gr/cm3, 2.52 gr/cm3, 1.482%, 3.644%, 3.31 μm, 16.24 μm, 20.03 μm, 8.958 cm3/50cm2 and 1004.03 kgf/cm2 respectively. The results show that the limestones in and around Tut (Adıyaman) county can be used in large areas for decorative purposes, with their physical and mechanical properties, as well as their colour tone and the texture formed as a result of the calcite veins being shaped like a natural pattern.

Throughout history, people have covered the floors of the buildings with materials such as carpet, rock pieces, wood, mosaic, ceramic and tile according to the conditions of the day due to their desire to protect them from moisture, make them hygienic environment easy to clean and give an aesthetic appearance. The merging of mechanization with cement based materials with the industrial revolution in the 19th century has brought along the development of diversity and different production methods in these floor covering materials. One of these coating materials is terrazo tiles that form the subject of the current paper. Terrazo tiles are materials obtained by pressing the mortar obtained by mixing water, cement, marble powder and aggregate in certain proportions. Within the scope of this research, it was aimed to provide alternative raw materials to the tile body and to transform the rock pieces, which are found in waste form in natural stone workshops, into the economy. For this purpose, geomaterials collected from magmatic, metamorphic and sedimentary rocks cropped in the Kahramanmaraş-Antakya-Elazığ regions and natural stone workshops operating in Kahramanmaraş city, were classified according to their geological origins and aggregates of 4.75-12 mm were obtained with the help of jaw crushers and sieves. Tiles have been produced in accordance with the method of tile production from sized aggregates. The produced tiles were kept in the water pool for 28 days and surface controls were made. According to the physical and mechanical test results applied to the tile samples, water absorption by weight is 5.31-13.25%, bending strength 4.95-8.89 MPa, Böhme abrasion resistance 1.09-3.43 cm3 /50 cm2 , mass loss after freeze-thaw is observed to be in the range of 0.97-1.59%. On the other hand, the surface roughness of the tiles prepared with coarse rock aggregates was found to be relatively lower than the tile samples obtained with fine grained rock aggregates. The obtained results indicate that the geomaterials subject to the research can be used as an alternative raw material source in tile production and these raw materials will provide new benefits to the construction field.

The paper presents physico-mechanical and hygienic parameters testing results of fabrics manufactured from bamboo cellulose fibres (100%) and their combination with cotton fibres (50/50%), as well as treated with: anti-pilling finish, anti-pilling and anti-shrinking finish, and dirt-repellent finish. They were evaluated on implementation in the footwear industry, comparing the results with the requirements for textile products intended for the lining/insole of children’s footwear and that of footwear for people with sensitive feet. The fabrics selected were also tested for microbiological resistance, and technological and functional tests of footwear manufactured with these fabrics were performed. It was assumed that the new range of fabrics would improve the physiological-hygienic comfort of the above-mentioned footwear. In laboratory tests, not all fabrics met the requirements, however their processing capabilities were positively assessed for the injection shoe assembly system applied. Promising results were also achieved by the footwear in the preliminary functional tests, for which fabrics made of cellulose bamboo fibres without any finishes were applied. Their usability was confirmed, i.e. resistance to abrasion and dirt, as well as the physiological-hygienic comfort of the footwear tested.

W pracy przedstawiono wyniki badań parametrów fizyko-mechanicznych i higienicznych tkanin wyprodukowanych z celulozowych włókien bambusowych (100%) oraz z mieszanki tych włókien z włóknami bawełny (50/50%), jak też poddanych wykończeniu apreturami: brudoodporną, przeciwpillingową oraz przeciwpillingową i przeciwkurczliwą. Oceniano je pod kątem wdrożenia w przemyśle obuwniczym, porównując wyniki badań z wymaganiami stawianymi wyrobom tekstylnym przeznaczonym na podszewki/wyściółki obuwia dla dzieci i dla osób ze stopami wrażliwymi. Wybrane tkaniny testowano także pod względem odporności mikrobiologicznej oraz w próbach technologiczno-użytkowych wyprodukowanego z ich udziałem obuwia. Założono, że nowy asortyment tkanin wpłynie na poprawę komfortu fizjologiczno-higienicznego wyżej wymienionego obuwia. W badaniach laboratoryjnych nie wszystkie tkaniny spełniły wymagania, jednak pozytywnie oceniono ich możliwości przetwórcze w zastosowanym wtryskowym systemie montażu obuwia. Obiecujące rezultaty dały także wstępne próby użytkowe obuwia, w którym zastosowano tkaniny z celulozowych włókien bambusowych bez jakichkolwiek apretur – potwierdzono ich przydatność użytkową, tj. odporność na ścieranie, odporność na brudzenie, jak też komfort fizjologiczno-higieniczny testowanego obuwia.

W artykule przedstawiono wyniki badań fizykomechanicznych i strukturalnych stali S690QL, które wskazują na możliwość stosowania tej stali w wyższych temperaturach eksploatacji niż wynika to z zaleceń normy PN—EN 10137:2000. Jednocześnie wskazano na niedociągnięcia technologiczne w procesie wytwarzania skutkujące niedostateczną jednorodnością materiału.

The results of physico-mechanical and structural tests carried out for the S690QL steel are presented in the paper. The tests indicated that this steel could be used in higher exploitation temperatures than recommended in the PN-EN 10137:2000 standard. Technical imperfections in production leading to material inhomogeneity are also shown.
