The results of the investigation of elastic properties of grained composite based on the unsaturated polyetheres were presented. This material was designed to substitute natural rocks in civil and mechanical engineering. The experimental values of elastic modulus and the Poisson's ratio under the tension and compression were obtained. It was shown that the investigated composite exhibits the dependence of elastic properties on the type of the stress state. It was suggested to use the simplest version of the theory of multimodulus isotropicmaterials in order to describe of the properties of these materials. This theory is based on the generalization of the classic isotropic potential for the case of the dependence of elastic properties on the type of the stress state. The parameters of the constitutive equations for the investigated composite were determined. The satisfactory correspondence between the values of the elastic deformation properties of the material calculated on the base of the considered constitutive equations and the experimental data was demonstrated.
