Significant activities have been carried out by the global research community to develop alternative sustainable building materials and energy efficient production methods, that result in more economical and sustainable building material production adhering to the comfort and aesthetic standards needed today. With the improvement of material science, polymer materials display application possibilities credited to their excellent properties compared with the inorganic materials, such as antibacterial, non-flammability, viscoelasticity, and sustainability. The main objective of this study was to improve quality and enhance the surface properties of building material surfaces. In the first part of this thesis, initiated chemical vapor deposition (iCVD) method was used to synthesize copolymer coating from 2,2,3,4,4,4-hexafluorobutyl acrylate (HFBA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) monomers to produce transparent anti-fog coating for mirror and glass surfaces. By eliminating solvent consumption, free radical polymerization was performed in the customized iCVD reactor. FTIR, XPS, VIS, and AFM characterization tests were performed to verify the copolymer anti-fog nanocoating. In the second part, a PVB-based polymer composite was developed for ceramic tile surfaces and dried at room temperature, which can be applied to glazed, unglazed, and porcelain ceramic tiles to enhance the properties of the tile surface. Functional polymer composite coating was used on the tiles instead of conventional glaze or other high temperature cured processes. Standard tile tests such as water, UV, abrasion, stain, and slip resistance test were applied to the polymer composite coated tiles that were passed successfully these tests to ensure the usage of coating in the industry. According to Rockwell scratch analysis, the composite containing Al2O3 filler particles had a higher hardness value than other filler particles.

Use of Geospatial Queries for Optimum Drilling and Blasting Practices in Surface Mining
Erkayaoğlu, Mustafa (2018-11-22)
Increasing demand of the modern society for energy and raw material strengthens the role of mining in sustainable development. The basic production cycle of surface mining is initiated by drilling and blasting the material that will be loaded, hauled, and dumped by various mobile equipment. Performance measurement and analysis of all these production stages by the utilization of available technology is of crucial importance for continuous improvement of modern mine operations. Today, most of the mobile equi...
Novel investigation of pyrolysis mechanisms and kinetics for functional groups in biomass matrix
Liu, Ruijia; Liu, Guijian; Yousaf, Balal; Niu, Zhiyuan; Abbas, Qumber (2022-01-01)
Biomass, as a renewable and sustainable energy resource, can be converted into environmentally friendly and practically valuable biofuels and chemical materials via pyrolysis. However, the process optimization and pyrolysis efficiency are restricted by the limited perception of the complicated mechanisms and kinetics for biomass pyrolysis. Here, to establish an in-depth mechanism model for biomass pyrolysis, we presented a novel investigation for the thermal evolutions and pyrolysis kinetics of the function...
Adopting sustainability assessment criteria to guide urban regeneraton projects: two case studies in Ankara
Seyhan, Zeynep.; Elias Özkan, Soofia Tahira; Department of Architecture (2019)
Increasing awareness of climate change, loss of biodiversity and increase in environmental pollution due to the current trends of consumption in the urban areas have brought about a myriad of schemas to guide environmentally friendly urban developments. These schemes or Neighborhood Sustainability Assessment Tools (NSA Tools) provide a convenient way to establish healthier and sustainable cities. Meanwhile, Turkey is going through a rapid urban transformation process that is being questioned with respect to...
Development of silica fume-based geopolymer foams
Shakouri, Sahra; Bayer, Özgür; Erdoğan, Sinan Turhan (Elsevier BV, 2020-11-01)
Thermal insulation materials are critical for reducing the energy consumption and carbon emissions associated with buildings. A good insulation material must not only have low density and sufficient mechanical properties but also resist high temperatures and fires. In addition, its production process must be simple and inexpensive. This study describes the production of very low density (>85 kg/m(3)) inorganic foams with high porosity (<94%). Silica fume and NaOH solutions are mixed to prepare a geopolymer ...
Motivators and barriers for green building construction market in Turkey
Gündoğan, Handan; Aydın, İsmail; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2012)
‘Green Buildings’ play an important role to increase the implementation of sustainable strategies in the construction industry. Although there is a process of change within Turkish building environment towards implementation of green strategies nowadays, limited research has been conducted to search the reasons that drive the market and the important barriers that block the green building movement. This thesis is intended to fill this gap in the literature and contribute to the field of knowledge regarding ...
