Resumo
A região de Minas Gerais é reconhecida como uma das maiores áreas de extração de minério de ferro do Brasil, que é o segundo maior produtor mundial. Durante a extração do mineral muitas toneladas de rejeito são geradas e estocadas em barragens. Paralelamente, um desafio no setor da Engenharia Civil e da Arquitetura é apresentar soluções construtivas que tenham um menor impacto ambiental. Dentre estas, tem-se a taipa de pilão como uma técnica construtiva com grande potencial sustentável devido a possibilidade de menor energia incorporada do que técnicas convencionais. Por conta dessa possibilidade de interação, a proposta do artigo é analisar a possibilidade da utilização de rejeito de minério de ferro (RMF) como estabilizante físico, atuando como corretor granulométrico da taipa de pilão. Não foram encontradas investigações a respeito do uso do RMF em taipa de pilão na construção civil. Constatou-se que é possível que o uso do RMF seja viável para correção granulométrica de solos da taipa de pilão ou substituindo algum material base. Isto acontece devido as características físicas, químicas e mineralógicas do RMF serem adequadas à técnica, sobretudo quando requerem porcentagens de areia, areia fina ou silte.
