Production of Pressed Brick of Cement Soil Manufactured with Addition of Construction and Demolition Waste

In this work the scientific study of the technical feasibility of the use of the soil of the city of Manaus for the production of soil-cement brick with addition of Construction and Demolition Residues (RCD) is verified. The soil characterization classified it as being clayey. For this soil to be employed it is necessary to correct it. In this context, as presented in the literature review, it is observed that Manaus produces large amounts of RCD, therefore it was decided to use the waste, as possible material to be used in soil correction. As presented in results and discussions, it is verified that the compressive strength of the bricks with RCD present values higher than the minimum values foreseen in standard. With these results obtained in the CP's and the adoption of the ideal trace, it is verified that the use of the RCD adapts the negative characteristics of the soil, demonstrating the viability of the production of soil-cement brick with addition of RCD.
