Sulfur polymer concrete (SPC) with its superior mechanical and durability properties has come to the fore in recent years as an alternative construction material to traditional Portland cement concrete (PCC). It is seen that the studies on the modulus of elasticity, which is an important design parameter of concrete, are insufficient in the literature for SPC and are still not considered in the prediction models suggested in the standards. This study aims to examine the compressive strength-modulus of elasticity relationship of SPC comparatively with analytical models proposed by international standards and traditional PPC. As a result of the experimental study, it was determined that the modulus of elasticity of SPC remained at lower values than PCC with similar compressive strength values. It was observed that the analytical models proposed in the standards for PCC could not obtain approximate values for the estimation of the modulus of elasticity of SPC, except for the ACI 363R-92 and NS 3473 standards. A new analytical model was proposed using the experimental data within the scope of this study. The proposed analytical model was statistically compared with the models in the standards that gave close results, and it was determined that the proposed model gave the closest results to the experimental values.
