BIOCONCRETO: DESENVOLVIMENTO TECNOLÓGICO E DURABILIDADE NA CONSTRUÇÃO CIVIL

Abstract

Concrete is the most used material in the world. It is a material with several advantages such as cost, ease of execution, adaptation to different formats, satisfactory resistance to atmospheric effects, thermal and mechanical resistance and extended useful life. Thus, bioconcrete technology is a multidisciplinary field of application of bioengineering to concrete that shows that the precipitation of microbial minerals can be beneficial to concrete. In view of this, this study aimed to analyze the technology of bioconcrete, with a view to performance regarding durability through results verified in compression, traction, bending and water permeability tests, verifying its feasibility for large-scale use in civil construction. The methodology used was a literature review. The results demonstrate that there was an improvement in the strength properties of concrete when bioconcrete is used, reaching in some cases an increase of 22.98% compared to conventional concrete. Regarding traction and flexion, a resistance increase of up to 35.43% and 51.32%, respectively, was evidenced. Another point of improvement in performance was the reduction of water permeability by up to 22.03% in bioconcrete. These results demonstrate that the use of bioconcrete presents satisfactory results when compared to conventional mixtures, being an excellent way to minimize damage to structures caused by cracks.
