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.

这项研究的预期成果是扩大加拿大木材的市场，方法是设计一种由玉米棒制成的新型建筑材料，一种混合了水和有机纤维的底土建筑材料，以及供发展中国家使用的木材。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）测量用于木材处理的八硼酸二钠（DOT）向粘土中的迁移，3）评估杉木-粘土材料在梁和木材-粘土小墙原型上的耐火性能，4）对木-粘土建筑的外壳进行热液模拟，5）进行可持续性分析，以突出在可持续发展的背景下使这种建筑选择有益和生态的条件，以及6）将结果传播给非洲需要社会住房的人。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作出贡献。这条新的加拿大木材贸易线有很大的潜力增加木材销售和加拿大木材在非洲的市场份额。
