    The Thermal Analysis of Plaster with Waste Expanded Polystyrene Gypsum and Resin
    (2023) Biçer, Ayse
    This study investigated the physical properties of plaster or decorative materials made of waste expanded polystyrene (EPS) and pine tree resin (as a binder). Thirty-two samples were produced by adding waste EPS in 0-3mm and 0-6mm grain diameters in two groups and at 20-80% addition rates and resin at 0, 0.5, 1, and 2% of the dry mix weight. Density, thermal conductivity coefficient, and compressive reduced by 50.64%, 82.68%, and 84.91% in samples with a diameter of 0-3 mm. Density, thermal conductivity coefficient, and compressive reduced by 51.03%, 86.55%, and 84.13% in samples with a diameter of 0-6 mm. Density and thermal conductivity decreased by 13.32-10.42% and 25.37-22.41%, respectively, while compressive strength increased by 29.50-19.56% in samples with a diameter of 0-3 mm and 2% resin. Density and thermal conductivity decreased by 19.60-13.68% and 17.24-10.25%, respectively, while compressive strength increased by 16.27-8.85% in samples with a diameter of 0-6 mm and 2% resin. The results show that the samples can be used as interior plaster, insulation plaster, and decoration material due to their grooving and paint adherence properties. This plaster and decoration material can help us i) reduce heating and cooling energy, ii) reuse waste EPS and prevent environmental pollution, and iii) reduce building load in tall buildings.

    Thermal and mechanical analysis of thermal power plant ashes, cement and resin composites
    (2023) Biçer, Ayse
    This study used thermal power plant fly ash (FA) and bottom ash (BA) as fill materials and investigated the thermal properties of composites made of cement and pine tree resin binders. For each ash group, 36 samples were prepared by adding 50% cement and 1% to 2% resin as binders. i) FA samples had 23.18%, 22.99%, and 77.01% lower density, thermal conductivity, and compressive strength than BA samples, respectively. FA samples had 9.42% higher porosity than BA samples. ii) FA (0.177 W/mK) and BA (0.221 W/mK) samples with resin and cement had the lowest heat transfer coefficients. iii) FA (14.46 MPa) and BA (36.96 MPa) samples (resin + cement binder) had the highest compressive strength values.

    Thermal and Mechanical Properties of Building Stones Used in Some provinces in the Marmara Region
    (2022) Biçer, Ayse
    In this study, some physical properties of Lefke (Bilecik), Keşan (Edirne), Çan (Çanakkale) and Küfeki (Istanbul) stones, which are used as building materials in their regions, were investigated. Samples were taken from two separate quarries for each stone, and after chemical analysis, thermal conductivity, compressive strength, water absorption, respiration ability and abrasion tests were performed. As a result of the tests, it has been revealed that i) Çan, Tüfekî and Lefke stones, among the ones examined, with low thermal conductivity coefficient values (0.342 W/mK, 0.564, 0.860 W/mK), can be used as briquettes, bricks or wall covering materials for thermal insulation and decoration purposes, ii) Keşan stone can be used in load-bearing wall material and wear-resistant flooring with 81.3 MPa compressive stress and 4.83% wear rate values and iii) four stones have rich reserves and low costs. The results were compared with other building materials especially in terms of energy saving, strength and comfort conditions.

    Thermal and Mechanical Properties of Concretes with Porous Aggregates
    (2021) Biçer, Ayse
    The results of an experimental study on the thermal and mechanical properties of concretes using porous aggregates instead of conventional aggregates are presented in this study. Oriented at this purpose, eleven concrete samples containing organic sediment stones, volcanic stones and artificial porous aggregates were prepared as porous aggregates. The concrete samples were subjected to certain tests at the end of 28 days of drying period and their thermal and mechanical properties were determined accordingly. With this study, the following values were obtained: i) The lowest heat transfer coefficient for concrete with expanded polystyrene aggregates from the group of artificial porous aggregates: 0.175 W/mK, ii) The highest compressive strength value is basalt-type stone (Karaca dag) from the group of volcanic stones: 117 MPa.
