This is a SGER proposal to complement the PI's NSF-funded International Research Experiences (NSF-IRES) program in the East African region. The overarching aim of the proposed research is investigating adaptations that can be made to existing earth bricks to improve their hygrothermal performance in hot and humid climates such as Dar es Salaam. This will be achieved through a series of laboratory testing complemented with advanced computer modeling. The specific research objectives focus on assessing how wall made out of earth bricks can be engineered for optimal performance with respect to: 1) Water vapor permeability; 2) Hygroscopicity, and; 3) Capillarity. The findings will be used to develop a computer-based model for predicting the performance of earth bricks.It is now universally acknowledged that organic building materials such as earth bricks are more sustainable. However, there are still doubts with respect to their adequacy as far as mechanical properties are concerned. The proposed SGER research will contribute to credibility of the properties of the existing earth bricks. A key outcome of the proposed SGER research will be a hygrothermal material property database for earth bricks which will be published on the Web. The research will also bring together a team of foreign experts who are currently working in silos. The PI will provide research training for a female, graduate student through the SGER.

这是一个SGER的建议，旨在补充东非地区NSF资助的国际研究经验（NSF-IRES）计划。拟议的研究的总体目的是调查适应，可以对现有的地球砖进行改善，以改善其在炎热和潮湿的气候（例如达累斯萨拉姆）中的湿热性能。这将通过一系列配有先进计算机建模的实验室测试来实现。具体的研究目标侧重于评估如何设计用地球砖制成的墙，以相对于以下方面的最佳性能：1）水蒸气渗透性； 2）吸湿性和； 3）毛细血管。这些发现将用于开发基于计算机的模型，以预测地球砖的性能。现在，它普遍认为，诸如Earth Bricks之类的有机建筑材料更可持续。但是，就机械性能而言，仍然存在对它们的充分性的怀疑。拟议的SGER研究将有助于现有地球砖的性能的可信度。拟议的SGER研究的关键结果将是将在网络上发布的地球砖的湿热物质属性数据库。这项研究还将汇集一个目前正在孤岛工作的外国专家团队。 PI将通过SGER为女性研究生提供研究培训。
