Análise da potencialidade de uso da escória de aciaria como matéria-prima alternativa na produção de pisos intertravados

Abstract

The main focus of this research is to analyze the potentiality to use steel slag in the production of interlocked floors. Aiming at the understanding of this study a field research is presented in order to deepen the knowledge on the importance of using this co-product as alternative raw material in new products and, above all, to promote sustainable development as a paradigm shift through its incorporation in the production of interlocked floors. The methodology involves field research, based on research carried out through three steps: the first one is the direct observation of the steel production chain located in the regions of Vale do Aço and Vale do Paraopeba, and interlocked flooring industries in the city of Pedro Leopoldo, Minas Gerais; the second analysis refers to a semi-structured interview and finally the third stage demonstrates the results achieved in the implementation of an electronic questionnaire directed to two types of audiences: experts in the co-products mills and manufacturers of interlocked floor. The interpretation of the results of this work demonstrates the potential to use this steel co-product as partial substitute element of natural aggregates gravel and sand for the production of interlocked floors. Following to this research it is suggested to glimpse into the possibility of future surveys, covering other types of application for steel slag, contributing to the sustainability in built environments. Ensuring the viability of use of steelmaking slag raw materials into new products is a complex task that requires multidisciplinary knowledge. In this sense, it is highly recommended the exercise of multidisciplinary research, given the fact that a growing number of publications have addressed the subject steel slag residue in several fields of knowledge.
