Análise da viabilidade do emprego da taipa de pilão para a execução de edificações no sul de Minas Gerais

Abstract

The public governance is striving for a stable and sustainable ecosystem, based on the concept of a “Smart City”. In the south of Minas Gerais, there is the city of Santa Rita do Sapucaí. It is located close to major economic hubs in Brazil, has an estimated population of 44.000 people, and aims to become a smart city. This city currently focuses on the development of these axes: Technology and Innovation, Education, and Entrepreneurship. The government developing incentive actions for the dissemination of constructions with a lower environmental impact, making them viable options for improving the city's infrastructure. Historically, there are earthen constructions throughout the state of Minas Gerais, mainly the wattle and daub, adobe and rammed earth techniques. These techniques are usually used in a mixed way, with great sustainable potential when incorporated with new technologies and materials. This research aimed to analyze the practicability of the rammed earth technique for the construction of buildings in the south of Minas Gerais, more specifically in Santa Rita do Sapucaí – MG, and its transformation into a smart city. The soil was extracted from the designated area, characterized, analyzed and corrected. Particle size distribution correction was performed with medium sand, due to the large number of fine materials present in the sample. No cement was added to the samples, which reduces embodied carbon. This was possible because the results obtained exceeded the technical resistance parameters of rammed earth. In conclusion, there are positive indications for the viability of the rammed earth technique as one of the construction possibilities to reduce environmental impact.
