Sustentabilidade na fabricação do tijolo solo-cimento: estudo comparativo com blocos convencionais

Abstract

The soil-cement brick, also known as ecological, appears as an element that concerns to meet the sustainable development of Civil Engineering. The study of this material is a way to promote an ecological, social and economic view, essencial for this sector. This study has as main purpose analyze the sustainability in the soil-cement brick manufacturing process in comparison to conventional blocks. The research is a qualitative methodological approach, carried out through a case study, in which the factories were determined to diagnose the manufacturing process of the studied materials. The soil-cement brick factory has resulted in significant differentials related to the ecological concerning to the reuse of waste from other construction-related sectors (builders and sand extractors) as the main raw materials. However, their production process presented issues that made sustainability unfeasible, such as improvised storage sites for raw materials, generating waste, besides the inadequate destination of part of the cement bags used, leading to environmental degradation by burning these materials. It was verified that the conventional blocks factories had sustainability characteristics not found in the cement-brick factory, obtaining greater viability about that. Improvement points regarding the organization and cleaning in the soil-cement brick production line can be performed so that its manufacturing becomes, in fact, more viable than the conventional blocks, contributing for a more sustainable future to the civil construction.
