This research attempts to substitute the fine aggregates with wastes type saw dust and shredded plastic bottles for obtaining green concrete by using local materials. The wastes of saw dust were from the wood industry while the chopped plastic bottles was a sub- product of the re-using plastic wastes process. The other materials were epoxy resin from Romanian industry, fly ash and natural aggregates. A control mix of polymer concrete was used for comparison. The experimental mixtures were prepared by substituting the fine aggregate with wastes in different percentages from 25% to 100%. The tensile tests were done for obtaining the flexural strength and splitting strength. The values of flexural strengths were bigger for polymer concrete with saw dust in comparison with chopped PET. For both types of wastes, the splitting strengths were bigger than that of the control-mixture.
