This study is concerned with the testing material for the properties of the thermal insulation of the vermiculite concrete. Through this experimental study, the vermiculite concrete is found that it is good quality for thermal insulating buildings, and that the building weight can be lightened by use of the vermiculite concrete, and the building cost can be saved, The result of this experimental study are follows: 1. The K-value of the vermiculite concrete are 0.243 - 0.614 Kcal/mh℃. 2. The specific gravity of vermiculite concrete are 1.4 - 1.75 and as the specific gravity in increased, the K-value is also increased. 3. As the W/C ratio of the vermiculite concrete is increased, the K-value is decreased accordingly. 4. As the rate of fine aggregate is increased, the K-value is increased accordingly.
