    ENVIRONMENTAL PROPERTIES OF ENVIRONMENTALLY FRIENDLY CONSTRUCTION MATERIALS: RECYCLED LDPE COMPOSITES FILLED BY BLAST FURNACE DUST
    (College Publishing, 2021) Kayili, Merve Tuna; Celebi, Gulser
    This study focused on creating a sustainable composite material using blast furnace dust of the iron-steel industry and plastic wastes of the plastic industry in order to reduce the embodied energy of the material and generate more sustainable material. In this study, varying amounts of blast furnace dust (BFD), which is the primary ironsteel industry waste and which is used as filler for recycled low-density polyethylene (LDPE), was mixed to create the composite material. The embodied energy, emissions to water and air (volatile organic compounds) of BFD filled LDPE composites were determined. It was found that the composite materials had less embodied energy compared with polymer-based flooring materials such as epoxy, polyurethane (PU) and polyvinylchloride (PVC). In addition, it was determined that the composite material did not release emissions to water and have fewer total volatile organic compounds (TVOCs). These results showed that the produced composite material could be used in buildings as a sustainable floor coating material, thus saving raw materials and supporting indoor air quality and recycling.

    MORPHOLOGICAL, MECHANICAL, THERMAL AND TRIBOLOGICAL PROPERTIES OF ENVIRONMENTALLY FRIENDLY CONSTRUCTION MATERIALS: RECYCLED LDPE COMPOSITES FILLED BY BLAST FURNACE DUST
    (College Publishing, 2020) Kayili, Merve Tuna; Celebi, Gulser; Guldas, Abdulmecit
    This study focused on developing a sustainable composite material using metallic wastes of the iron-steel industry and plastic wastes of the plastic industry in order to reduce resultant waste from the production processes of various industrial products and to sustain waste management of these industries. In this study, different amounts of blast furnace dust (BFD), which is the major iron-steel industry waste and is used as filler for recycled low-density polyethylene (LDPE), was mixed with LDPE to produce the composite material. The morphology, mechanical, vicat softening temperature thermal conductivity, hardness and wear resistance properties of BFD filled LDPE composites were assessed. The increasing of BFD in recycled LDPE improved the heat resistance, increased thermal conductivity and wear resistance of composite materials. In addition, it was found that the composite materials had sufficient mechanical properties, when mechanical tests were evaluated. These results showed that the produced composite material could be used in buildings as a floor coating material and thereby saving raw materials and resources, as well as potentially reducing environmental problems.

    RESPONSIVE KINETIC FACADE STRATEGY AND DETERMINATION OF THE EFFECT ON SOLAR HEAT GAIN USING PARAMETRIC BIM-BASED ENERGY SIMULATION
    (College Publishing, 2022) Salah, Fadi; Kayili, Merve Tuna
    This research investigates the potential of kinetic facade reinforcement strategy to reduce the energy consumption of existing buildings in a cold-dominated zone by lowering the cooling load with a mobile solar control system and effective solar control. In this context, a kinetic facade system was proposed for a public building with high transparency in Karabuk, Turkey, and the fixed shading elements of the existing building were compared with solar heat gain. For the kinetic facade scenario, the study workflow was developed by a visual programming environment in a Building Information Modeling (BIM) application. The flexible movement of individual kinetic panels was determined by the kinetic panel opening factor and sun path. To determine the effect of typological differences on solar control in the kinetic facade system, horizontal kinetic folded panels and vertical kinetic folded panels were investigated. As a result, a reduction of up to 11.52% was found in solar heat gain during the highest solar radiation intensity days for the existing public building.
