Resin concrete is increasingly used in machine tool structures in order to improve the dynamic properties and to reduce the lead time of production. However, it has been pointed out that the thermal and mechanical characteristics of resin concrete are not clarified as yet. In this paper, the thermal conductivity, the specific heat, the coefficient of linear expansion, the Young's modulus and the Poisson's ratio of epoxy resin concrete have been experimentally investigated, and also some theoretical models have been investigated to calculate the thermal and mechanical characteristics. It is concluded from the result; that the thermal and mechanical characteristics of epoxy resin concrete depend strongly on the constituent materials; the relationships between characteristics and constituents are clarified to some extent. It is confirmed that the proposed models can be used to estimate some of the fundamental thermal and mechanical characteristics from the physical properties and volume fluctuations of the constituent materials, which can be used for designing an appropriate resin concrete.
