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.<br/> 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.<br/> 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.

Recently, as the alternatives to preserve environment such as effective usage of wastes or unusable resources are drawing attentions, researches and measures for the two tasks, which are reuse of waste wood and development of eco~friendly materials, are being examined and established in various fields. However, they are still insufficient. Therefore, in this study, for the efficient application of waste woods and eco~friendly effects, mortar was produced using sawdust as the waste wood and mineral material cement for combination, in order to produce inorganic boards using waste woods, which were made when sawing. The present study purposed to analyze the physical and dynamic characteristics of woody cement boards, which were made by modifying water~cement ratio for each wood inclusion rate based on a hardening~accelerator inclusion rate set in previous studies and, based on the findings, to provide basic data about the physical properties of inorganic boards made of waste wood, in order to produce woody cement boards using waste wood, which has problems in being used in the manufacturing of woody cement boards.

This study attempted to suggest a basic material about the physical properties of mortar, which used waste woods, after examining the features of wood mixture rate, water-cement rate, congelation according to the mixture rate of the setting accelerator, specific gravity, compression intensity, and bending intensity as experiment factors.

Most concrete is recently made of an aggregate which is properly absorbed, and carried in it in order to do capability at every fields. We have been close to demand new capability of high flowing and enduring for specific concretes. That is difficult to cope with claiming the efficiency on deterioration from lack of a high quality aggregate. Therefore, For solving the problems we apply to a packing method for using dried materials. That is to say it is a kind of making into an instant. In this study, There is a purpose to present fundamental data, comparing and analyzing a phenomenon about aggregate's absorption following the rate of adding water, for using existing materials.
