The experimental work developed begins with the preparation and sampling of a single concrete pattern design and three antibacterial concrete designs with different dosage of Antimicrobial Additive, which are evaluated through a microbiological test. This consists in the exposure of the concrete samples at the consortium of bacteria present in a wastewater treatment plant. The effectiveness of the additive under study was determined by a visual analysis of the coloration, pH variation and then compared to the results of the concrete pattern design. As an alternative solution for sulfuric acid attack, the preparation, sampling and control of six concrete designs was carried out in laboratory, for which some study variables were established: the water / cement ratio and the mineral addition percentage of Filler Limestone. The durability of the concrete was evaluated by hardened destructive and non-destructive tests. Likewise, the resistance of the concrete was determined against concentrations of 3%, 5% and 7% of sulfuric acid, for an exposure time of 4 and 8 weeks and analyzed by the weight loss. Finally, an economic evaluation was carried out based on a sanitary project, in which the budget for the construction of mailboxes was determined considering the costs of the standard and antibacterial concrete previously chosen. To determine the benefit, a schedule was established with the items of preventive and corrective maintenance according to the frequency and necessity of each design. The results were presented through a flow of expenditures for a period of analysis of 20 years.
