Análise da substituição parcial do cimento pelo Resíduo de Beneficiamento de Mármore e Granito (RBMG) na produção de concretos

Abstract

The construction industry is characterized as the main consumer of natural resources, however, has great potential for the use of waste and industrial by-products in the production of construction materials. In this context, the present research aims to use the marble and granite beneficiation residue (RBMG), generated by the ornamental stone industry, as a partial cement substitute in concrete. For this, the RBMG 5, 7.5 and 10% substitution contents were tested in relation to the cement volume in the trait. Regarding the mechanical properties of compressive strength and tensile strength of the concrete produced, the traces with contents of 5 and 7.5%, obtained results above the reference concrete. Only in the absorption test the concrete with 10% presented results above the pilot line. Overall, research indicates the technical feasibility of partially replacing cement with RBMG in the production of concrete.
