This research project was carried out in the Civil Engineering laboratories - UPC, and the biological laboratory – UNMSM; with the clear objective of experimenting and confirming the initial hypothesis: “The Bacillus Subtilis bacteria added in concrete mix design (bioconcrete), is capable of producing calcite, accordingly, self-repair the cracking of Atarjea decanters. The concrete sooner or later crack due to various causes, be it due to the climate, the humidity, that exists in the city where the work is located, due to the pH, due to moderate intensity seismic movements, etc. This investigation was focused on repairing with an innovative construction material (bio-concrete) the cracks in the decanters of the Atarjea, which are the ones that cause the most expenses in repairs. All data for the development of this research were obtained through the design of protocols: biological part (bacteria: isolation, culture, reproduction, sporulation), engineering part (mix design and concrete tests: resistance, granulometry, humidity, etc.) The bio concrete was made for a mix design with f´c = 210 kg/cm2, with slump of 4'' and complying with the standard ACI 211. With this investigation it was possible to verify, that bio concrete, reaches its resistance after 28 days, and self-repair fissures and cracks effectively, with a tendency to decrease the width of 0.20 mm by month, this means, that the initial hypothesis is feasible and viable.
