Abstract
Dada la actual situación medioambiental, se ha vuelto cada vez más precisa la incorporación de materiales sustentables dentro del mundo de la construcción; industria responsable en gran parte de la generación de gases de invernadero. Es por esto que dentro de las tecnologías que se han ido desarrollando, un hormigón auto-reparable por bacterias, aumentaría la vida útil de las estructuras, disminuyendo así los costos, gastos energéticos e impactos ambientales asociados a la reparación.La presente investigación analiza algunas de las condiciones ambientales a las que se podrían enfrentar los microorganismos responsables de la auto-reparación y verificar su eficacia y por ende su posible aplicación.La utilización de la bacteria Bacillus Pseudofirmus muestra una mejora en grietas de hasta 0.38 mm a temperaturas de 23°C, lo que posibilita su utilización en climas cálidos. Respecto a los resultados obtenidos en cada tipo de cemento, se muestra levemente un mejor desempeño para el cemento Portland, en comparación al Puzolánico.
Given the current environmental situation, the incorporation of sustainable materials within the field of construction has become a necessity. The industry is responsible for a large amount of the emanation of greenhouse gases. Thanks to the progress in Microbiology we have access to the technology that enables us to produce self-healing concrete by bacteria. This material will prolong life of structures, reducing the cost, energy and environmental impact of maintenance on the structures.The present investigation analyzes some environmental conditions where the microorganism is effective and will repair the subject. Furthermore, these analyzes allow us assess behavior of the bacteria and therefore we can classify it for future application.The use of Bacillus Pseudofirmus bacteria shows an improvement in cracks of up to 0.38 mm at temperatures of 23 ° C, which allows its use in warm climates. Regarding the results obtained in each type of cement, it shows a slightly better performance for Portland cement, compared to Pozzolanic cement.
