Concrete is the most-used building material in world and a biologically extreme environment, with microbiome composed of bacteria that likely come from concrete precursor materials, aerosols, environmental deposition. These microbes, though seeded variety are all subject to desiccation, heating, starvation, high salinity, very pH.
