In order to apply polymer concrete as a new structural material to machine tool structures, basic studies are carried out to obtain optimum design strategy of concrete. The relations are experimentally obtained between the weight percentage of the fine aggregate within the aggregates and the volume percentage of the total aggregates filled in limited volumes. Cylindrical specimens made of epoxy resin concretes with various compositions are tested to compare static and dynamic rigidities and tensile strength. Major results obtained are as follows : (1) There exists an optimum weight percentage of the fine aggregate taking into account of the sizes of the aggregates and the volume to be filled. (2) When the content of the resin in the concrete is increased, the damping of the concrete specimen is increased, while the rigidity is decreased. The effect of the resin content is much critical to the change of the rigidity than to that of the damping. (3) The tensile fracture of the concrete is mainly attributable to the fracture of the coarse aggregate. Thus the tensile strength of the concrete specimen is higher for that with larger weight percentage of the fine aggregate.
