Abstract With environmental contamination and the exhaustion of natural resources due to the rapid industrialization, there are growing concerns over the preservation of the environment and resources and as a result research on recycling wastes such as wood waste is being actively carried out. Thus, in order to promote the effective use of wood waste and to examine the characteristics of cement boards that are made of wood waste from wood, an environment-friendly material, and can be used as insulating and fire-proofing materials, this study purposed to investigate the properties of mortar made of sawdust and cement, which is an inorganic material used as a binder, to determine the optimal proportion of congelation accelerator, and ultimately to provide basic materials on the physical properties of woody cement boards. According to the result of this study, the most economically efficient proportion of congelation accelerator CaCl2 is 4%, and when the proportion of wood increases the specific gravity of cement boards goes down and physical properties such as heat conductivity are improved.
