Dielectric properties of straw walls and the thickness suitable for the construction of a straw wall building

Abstract

The objective of this research is to study the dielectric properties of straw walls. And suitable thickness to prevent heat for the construction of straw walls in Thailand From the study of the wall properties made from rice straw, it has the potential to Is an insulator preventing heat from entering the building The straw walls also use rice straw, which is a waste product from agriculture. Rice is the main agricultural crop in Thailand, the rice straw as agricultural waste in all regions of Thailand.

        The study is divided into two parts. The first part is to study the thermal conductivity behavior of the dense compressed straw walls. Is compressed with human power and compressed by machine power from then, the data obtained is the data to simulate the thickness of each straw bale using computer simulation system Computational Fluid Dynamics

        The results of the research show that the straw wall has insulating properties. The test box uses straw walls with a thickness of 0.20 meters. The straw walls are pressed by machine power with density of 101.43 kilograms / cubic meter. And straw walls pressed from human strength with a density of 67.14 kg / cubic meter. It was found that the density of both straw walls had similar behavior, which could delay the heat in the straw wall for about 20 minutes, allowing the heat to flow slightly to the other side. Therefore taking the information from the experiment box Build models to find suitable wall thickness. Computer program it was found that the thick walls of 0.10, 0.20, 0.30 and 0.40 meters have similar heat protection properties.
