Análise das propriedades físicas do rejeito de bauxita como insumo para a fabricação de tijolos solo cimento

Abstract

The mining sector has been exploring and generating a high volume of waste that is that cause of several environmental problems in the world, especially in Brazil. Thus, it is increasingly necessary to search for new alternatives for the use of these wastes to minimize the impacts generated by their disposal. One of these applications is the use in the manufacture of soilcement brick or ecological brick. The objective of this study is to analyze the feasibility of the physical characteristics of bauxite tailings for total replacement of the soil in the manufacture of ecological bricks, combining low cost and sustainability. The research methodology was quantitative using the case study approach. Regarding the nature, the study is of applied nature, being exploratory research. The results revealed that the mixture between the studied waste in the proportion of 1:1 meets the physical parameters that enabled its use in the manufacture of soil-cement bricks.
