This research was carried out to determine the effect of effective microorganisms EM-1 on the compressive and flexural strength of concrete f'c=210 kg/cm2, a percentage of water was replaced by EM-1 according to its mix design. A total of 120 concrete specimens were made, consisting of 4 mixtures: Standard Concrete (CP), Concrete with 2% of EM-1 (CP2EM), Concrete with 5% of EM-1 (CP5EM) and Concrete with 10% of EM-1 (CP10EM). Of these, 60 were cylindrical specimens and 60 were prismatic specimens, which were subjected to compression and flexural tests respectively at 7, 14 and 28 days. In addition, characterization techniques such as Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectrometry (EDS) and X-Ray Diffraction (XRD) were applied to fragments belonging to the specimens. The results showed that the concrete with 10% EM-1 (CP10EM) performed better in compressive and flexural strength of the concrete by 12.14% and 16.64%, respectively, with respect to the standard concrete (CP). Characterization techniques performed on the concrete samples suggest that the strength improvement was due to the segregation of calcium carbonate (CaCO3) in the concrete matrix
