Description: The processing of industrial hemp, cannabis sativa, results in three basic constituents ? seed, fibre, and hurd. Within the Manitoba context the main focus has been with the grain market and the processing of the seed for oil-based products. When considering the entire plant approximately 60-70% is the predominantly cellulose woody core called the hurd. A combination of hemp hurd, lime, cement and water in various proportions has been used for centuries in the construction of buildings. In the current vernacular it is often referred to as ?hempcrete?. Hempcrete is used as an environmental barrier providing resistance to heat transfer and to manage moisture by allowing the wall to breathe. Engineering and architectural designers practicing in the field of non-conventional material applications have clearly indicated a need for design data. A total of 127 specimens were tested to determine the load-deformation behaviour of hemp hurd with a cementitious binder. Seven binder mixes used with Manitoba-produced hemp hurd were evaluated. Upon completion of the baseline testing one mix design is currently being used in the construction of a test building located on the Alternative Village at the University of Manitoba to evaluate thermal performance in a northern prairie climate. This paper presents the results of the testing.
