| Abstract Scope |
The construction industry is the human activity that consumes the most natural resources. This occurs from before the beginning of the work, with the extraction of minerals for production of aggregates and cement. Considering the high consumption of materials in the construction and the durability of the buildings, the continuous generation of CDW (Construction and Demolition Waste) presents itself as a problem. The objective of this work is to verify the influence that the incorporation of CDW promotes in the concrete properties. The CDW was incorporated into 50% and 100% replacement of natural sand. Materials and concrete characterization tests were performed by slump test, water absorption by immersion, water absorption by capillarity and mechanical strength. The tests indicated that the presence of CDW improves the performance of the concrete, increasing its resistance and decreasing its water absorption. |
