Abstract: The paper discusses the use of autoclave as acceleration method for increasing the strength of bioconstruction materials. Three mixes where studied, they were prepared in order to have a CaO/SiO2 around 1. Hemp fibers were mixed with three different binder, Lime and silica fume mix (CaO/SiO2 = 1), cement and silica fume mix (CaO/SiO2 = 0,96) and cement, silica fume and lime mix (CaO/SiO2 = 0,95). Two curing temperature (110°C, 130°C and 180°C) used. The results show an increase of the strength of lime and silica fume mix from 0,5MPa to 4,4Mpa after autoclave at 110°C. While the cement and silica fume has an increase from 0,8Mpa to 1,5Mpa after autoclave at 110°C. The same mixes at autoclave 180°C show smaller increase in strength than autoclave at 110°C.
