The paper presents the results of studying the hardening processes of concrete based on Portland cement using biocementing additives. Isolated 11 strains of various bacteria were used as dietary supplements. The bacteria were grown at a temperature of 30 °C in an aerated fermenter with a stirrer speed of 550–600 rpm. The morphology of the concrete surface was evaluated before and after the application of the substrate with the nutrient medium; the appearance of a new phase was recorded after 2 weeks. The effect of cementation conditions on the compressive strength of biocemented concrete specimens was studied, and the capillary water`s coefficients absorption were determined.
