Öğe Assessment of the sustainability and producibility of adobe constructions reinforced with Ca-based binders: Environmental life cycle analysis (LCA) and 3D printability(Elsevier, 2024) Genc, Gokhan; Demircan, Ruya Kilic; Beyhan, Figen; Kaplan, GokhanThis study investigated the usability of adobe samples reinforced with calcium-based binders in a 3D-printed technique. These adobe samples' physical, mechanical, durability and microstructure characteristics were investigated and their 3D printability characteristics experimentally. In the case of adobe production by 3D -print-ing method, the compressive strength decreased by 9-33 % compared to mold casting. While the thermal con-ductivity coefficient of adobe samples varied between 0.833 and 1.421 W/mK, the thermal conductivity was reduced by 43 % thanks to the preference for gypsum. Within the scope of the LCA analysis, the slightest effect in terms of environmental damage was observed in mixtures containing gypsum compared to cement and slaked lime mixtures. As a result, it was determined that adobe's physical and mechanical characteristics could be improved by using gypsum, lime and cement, and these mixtures can be used in 3D-printing. It was determined that more sustainable adobe production is possible with gypsum and lime.Öğe Eco-efficient lime/pumice mortars with sheep wool for heritage restoration: Life cycle and energy savings(Pergamon-Elsevier Science Ltd, 2025) Demircan, Ruya Kilic; Isik, Muhammet Ahmet Mecit; Benli, Ahmet; Genc, Gokhan; Beyhan, Figen; Kaplan, GokhanCurrently, 40 % of CO2 emissions and energy use are attributable to the building sector. Aside from thermal insulation levels and energy requirements, primary energy consumption, CO2 reductions, and the environmentally friendly properties of the materials used are currently being considered when evaluating building sustainability and energy efficiency. Therefore, it is essential to optimize the use of ecological materials in buildings in order to make them as sustainable as feasible. Utilizing slaked lime and pumice powder as binders, nine distinct types of mortars reinforced with sheep wool fibers with comparable workability were examined. This research assessed the fresh, physico-mechanical, durability, life cycle assessment and thermal properties of restoration mortars reinforced with wool fibers and containing pumice powder in place of slaked lime at 0, 25, and 50 % replacement rates. The three percentages of wool fibers by volume that were used in this investigation were 0, 0.25 and 0.50 %. It was also investigated how well the combinations held up to high temperatures, dry shrinkage, and sorptivity. Microstructural analysis of the mixtures were made based on SEM. The findings indicated that the mixture with 50 % pumice powder and 0 %wool fibers showed the best compressive strength performance, exhibiting a strength gain of approximately 953 and 643 % in comparison to the control mixture at 28 and 90 days, respectively. The same mixture also demonstrated the lowest sorptivity and dry shrinkage, while the reference blend exhibited the lowest thermal conductivity. The mixture with 50 %PP and 0.50 %wool fibers showed the best high temperature performance.Öğe Eco-efficient lime/pumice mortars with sheep wool for heritage restoration: Life cycle and energy savings (vol 215, 115624, 2025)(Pergamon-Elsevier Science Ltd, 2026) Demircan, Ruya Kilic; Isik, Muhammet Ahmet Mecit; Benli, Ahmet; Genc, Gokhan; Beyhan, Figen; Kaplan, Gokhan[No abstract available]
