Abstract

The energy deficiency in rural housing in the Andes of Peru is recurrent. In this context, local and low environmental impact materials present an opportunity. This research evaluated the properties of five panels composed of totora and gypsum for ceiling applications. Firstly, the physical and durability properties were obtained. Then, impact and fire resistance were evaluated. Finally, thermoacoustic properties were assessed. The results showed a moisture level of 10.25%, water absorption of 354.85% which is considered high, and a dry density of 292.84 kg/m3. Adequate durability to fungus with resin on both sides. The panels’ fire resistance is superior to 60 minutes, with a safe impact criterion for 10 N and a functionality criterion for 5 N. The average values for the panels were 0.061 W/m·K for thermal insulation and 0.54 for NRC. Therefore, it is possible to produce an insulating material for thermoacoustic improvement.

由totora和石膏制成的生态高效热声板，用于可持续农村住房天花板

秘鲁安第斯山脉农村住房的能源短缺是经常发生的。在这种情况下，本地和低环境影响的材料提供了一个机会。本研究评估了五种由totora和石膏组成的天花板板的性能。首先，获得了材料的物理性能和耐久性。然后进行了抗冲击性和耐火性评价。最后，对其热声性能进行了评估。结果表明，其含水率为10.25%，吸水率为354.85%，为高吸水率，干密度为292.84 kg/m3。有足够的耐用性真菌与树脂两面。面板的耐火性能优于60分钟，安全冲击标准为10 N，功能标准为5 N，保温面板的平均值为0.061 W/m·K, NRC面板的平均值为0.54。因此，生产一种热声改善的绝缘材料是可能的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
