The properties of old concrete are important factors in the seismic evaluations of these buildings. For this study, concrete pieces were obtained from an existing RC building constructed at 1969. This paper mainly discussed the mechanical properties, carbonation rate and mix properties of the concrete. The compressive tests, tensile splitting tests, pull-out tests, componential analysis of concrete, and carbonation tests were performed. In addition, the observed values were compared with the present standard and various estimation equations.
