Compression tests were performed to determine strength and stiffness, as well as ultrasound tests by direct and indirect method on concrete produced with different concentrations of synthetic polymer. The results suggested a decrease in the mechanical and acoustic properties of concrete with the increase in the concentration of synthetic polymer. The models generated by the ultrasonic test were statistically significant, at 95% confidence level, and the correlations established in concrete can be applied in the detection of pathological manifestations in loco.
