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 indeveloping countries. The project will address the housing deficit in Africa and benefit those that would notnormally have access to engineering research. The six specific objectives are 1) to formulate a mixture of claywith plant fibres for construction in order to measure thermal and hygrometric properties, 2) to measure themigration of disodium octaborate (DOT) used in the wood treatment into the clay, 3) to evaluate thefire performance of fir-clay materials on a beam and on a prototype of a wood-clay small wall, 4) to performhydrothermal modelling on the envelope of wood-clay buildings, 5) to conduct sustainability analyses to highlightthe conditions that make this choice of construction beneficial and ecological in the context of sustainabledevelopment, and 6) to disseminate the results to those needing social housing in Africa. At ETS, two PhDsand one Master student will complete objectives 1, 2, 4, 5 and 6. Objective 3 will be the responsibility of oneMaster student at York University who will also contribute to objective 6. This new tradeline for Canadianwood has great potential to increase wood sales and the market share of Canadian wood in Africa.

该研究的预期成果是通过设计一种由玉米芯制成的新型建筑材料（一种与水和有机纤维混合的地下建筑材料）以及供发展中国家使用的木材来扩大加拿大木材的市场。该项目将解决非洲的住房短缺问题，并使那些通常无法获得工程研究机会的人受益。六个具体目标是 1) 配制用于建筑的粘土与植物纤维的混合物，以测量热和湿度特性，2) 测量木材处理中使用的八硼酸钠 (DOT) 向粘土中的迁移，3) 评估冷杉粘土材料在梁上和木粘土小墙原型上的防火性能，4) 对木粘土建筑的围护结构进行水热建模，5) 进行可持续性分析强调在可持续发展的背景下使这种建设选择有益且生态的条件，以及 6) 将结果传播给非洲需要社会住房的人们。在 ETS，两名博士生和一名硕士生将完成目标 1、2、4、5 和 6。目标 3 将由约克大学的一名硕士生负责，他也将为目标 6 做出贡献。加拿大木业的这条新贸易线具有巨大的潜力增加木材销量和加拿大木材在非洲的市场份额。
