Abstract

Given the current environmental situation in Ecuador, it has become increasingly necessary to incorporate sustainable materials in the construction industry, which is largely responsible for the generation of greenhouse gases. This is why within the technologies that have been developed it is important to analyze and verify the feasibility of the use of certain sustainable materials, such as the appearance of self-repairing concrete by bacteria, increasing the useful life of the structures, thus reducing costs, energy costs and environmental impacts associated with the repair is one of the possible aids to the future of society. This research analyzes one of the conditions that one of the microorganisms responsible for self-repair could face when absorbing cracks in rigid pavement and verifying its effectiveness in the place delimited in this project and therefore its possible application as a bacterial additive in the presence of cracks in concrete commonly used in the country, as well as listing the properties of resistance (compressive strength and flexural strength) and durability (size of cracks) of concrete. It was concluded that the Bacillus Pseudofirmus strain can be used as a bacterial additive since favorable results have been obtained for concrete, thus demonstrating that the use of Bacillus Pseudofirmus bacteria shows an improvement in cracks of up to 0.38 mm at temperatures of 23°C, which makes its use possible in warm climates.
