Resumo: |
Given the imminent shortage of available natural resources and environmental problems arising from inadequate irregular deposition of waste in urban centers, this paper seeks to analyze the physical characteristics of blocks and aggregates, construction waste and demolition RCD from industry of construction and demolition of municipality of Petrolina-PE. The construction as any other productive sector is to produce waste due to waste and the demolition after use or disasters. One application for the residue is added as an alternative to replace all or part of natural, used for the production of blocks. The use of waste as aggregates for mortar and concrete do not have enough structural studies disseminated in the Brazilian and worldwide. In this work, we analyzed the feasibility of making the blocks with the use of recycled fine aggregate for use in masonry sealing and performance in the face of blocks with natural aggregates, manufactured in the municipality of Petrolina, using a dash pattern 1: 6 (cement: aggregate kid). The results indicated that replacing 25; 50; 75; and 100% of natural sand by recycled fine aggregate did not significantly affect the mechanical properties of blocks, whose resistance values reached 3,67 MPa, 2,63 MPa, 2,44 MPa e 2,03 MPa respectively. On the other hand, such replacement presents high porosity, requiring more detailed studies in order to minimize this effect for which to obtain greater durability of buildings constructed with that composition |
