Development and assessment of performance, fire safety, and sustainability of wood-clay materials for construction of housing in Africa

这项研究的预期结果是通过设计一种新型的建筑材料来扩大加拿大木材的市场，这种材料由木芯、一种混合了水和有机纤维的底土建筑材料以及用于 发展中国家。该项目将解决非洲的住房短缺问题，并使那些不愿 通常可以接触到工程研究。六个具体目标是：1)配制一种粘土混合物 使用建筑用植物纤维，以测量热和湿性能，2)测量 木材处理中的八硼酸二钠(DOT)在粘土中的迁移，3)评价 杉木粘土材料在梁上和木质粘土小墙原型上的防火性能，4)表演 对木质粘土建筑的围护结构进行水热模拟，5)进行可持续性分析以突出 在可持续的背景下，使这一建设选择有益于生态的条件 6)向非洲需要社会住房的人传播这一成果。在ETS，两名博士 一名硕士研究生将完成目标1、2、4、5和6。目标3由一人负责 约克大学的硕士研究生，也将为目标6做出贡献。加拿大的这一新贸易 木材在增加木材销售和加拿大木材在非洲的市场份额方面具有巨大潜力。

The intended outcome of the research is to expand the market of Canadian wood, by designing a novel building material made of cob, a subsoil building material mixed with water and organic fibre, and wood for use in developing countries. The project will address the housing deficit in Africa and benefit those that would not normally have access to engineering research. The six specific objectives are 1) to formulate a mixture of clay with plant fibres for construction in order to measure thermal and hygrometric properties, 2) to measure the migration of disodium octaborate (DOT) used in the wood treatment into the clay, 3) to evaluate the fire performance of fir-clay materials on a beam and on a prototype of a wood-clay small wall, 4) to perform hydrothermal modelling on the envelope of wood-clay buildings, 5) to conduct sustainability analyses to highlight the conditions that make this choice of construction beneficial and ecological in the context of sustainable development, and 6) to disseminate the results to those needing social housing in Africa. At ETS, two PhDs and one Master student will complete objectives 1, 2, 4, 5 and 6. Objective 3 will be the responsibility of one Master student at York University who will also contribute to objective 6. This new tradeline for Canadian wood has great potential to increase wood sales and the market share of Canadian wood in Africa.
