Abstract

Bu çalışma, atık genleşmiş polistiren (EPS) ve çam ağacı reçinesinden (bağlayıcı olarak) yapılmış sıva veya dekoratif malzemelerin fiziksel özelliklerini araştırmıştır. İki grup halinde 0-3 mm ve 0-6 mm tane çaplarında atık EPS ve kuru karışım ağırlığının %20-80'i oranında reçine ve %0, 0.5, 1 ve 2 oranında reçine ilave edilerek 32 adet numune üretilmiştir. 0-3 mm çaplı numunelerde yoğunluk, termal iletkenlik katsayısı ve basınç %50.64, %82.68 ve %84.91 oranında azaltılmıştır. 0-6 mm çapındaki numunelerde yoğunluk, ısıl iletkenlik katsayısı ve basınç %51.03, %86.55 ve %84.13 oranında azalmıştır. 0-3 mm çapında ve %2 reçineli numunelerde yoğunluk ve ısıl iletkenlik sırasıyla %13.32-10.42 ve %25.37-22.41 azalırken basınç dayanımı %29.50-19.56 artmıştır. 0-6 mm çapında ve %2 reçineli numunelerde yoğunluk ve ısıl iletkenlik sırasıyla %19.60-13.68 ve %17.24-10.25 azalırken, basınç dayanımı %16.27-8.85 artmıştır. Sonuçlar, numunelerin kanal açma ve boya tutma özelliklerinden dolayı iç cephe sıvası, yalıtım sıvası ve dekorasyon malzemesi olarak kullanılabileceğini göstermektedir. Bu sıva ve dekorasyon malzemesi kullanılarak i) ısıtma ve soğutma enerjisinin azaltılması, ii) atık EPS'yi yeniden kullanmasına ve çevre kirliliğinin önlemesine iii) yüksek binalarda bina yükünü azaltmasına yardımcı olacaktır.

The Thermal Analysis of Plaster with Waste Expanded Polystyrene Gypsum and Resin

Abstract

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.
