In order to improve the mechanical properties and decrease the manufacturing costs of traditional polymer concrete, a new concrete mix is presented, where fine silica sand is used instead of common large and small aggregates. In addition, to decrease manufacturing costs, a polyester resin is employed instead of epoxy matrix. By performing compression and three-point bending tests, it was found that the new polymer concrete had a higher compression strength than the traditional polymer concrete and a similar bending strength. Also, a two-phase micromechanical model was used to analytically estimate the compressive strength of the new material, and a rather good agreement between experimental data and theoretical calculations was found to exist.
