Seashell Waste, Composite, Temperature, Galvalume RoofAbstract
This research focuses on the characteristics provided by the composite layer applied to galvalume roof as a coating with the addition of seashell waste when subjected to temperature. Galvalume roof has a significant drawback where heat penetrates the house, causing discomfort. The primary objective of this study is to determine the characteristics of the seashell waste addition on the composite layer when exposed to heat. This research is using a true experimental method with graphic analysis, including galvalume specimens, 100% resin, weight fraction between the seashell waste and the composite layers 20%:80%, 30%:70%, 40%:60%, and 50%:50%. The results obtained from the research show that seashell waste has a major content of CaCO3 at 95,44%. Thermal conductivity testing reveals that the galvalume specimen has a thermal conductivity of 9,391 W/m°C, while 50%:50% has 0,24 W/m°C. In the temperature testing, it was found that the 50%:50% specimen has the ability to suppress the temperature by 5,49 °C compared to the galvalume specimen.
