Soil characterisation used in ceramic industries and an analysis of its feasibility in ecological bricks

n this study, we aimed to characterise soils of three sedimentary deposits used as raw material sources for ceramic industries located in the Brazilian semi-arid region. The samples were collected in deposits located in the cities of Barra de São Miguel, Juazeirinho and Santa Cecília. They were name...

The samples were collected in deposits located in the cities of Barra de São Miguel, Juazeirinho and Santa Cecília.
