Population growth increases consumption, causing a high generation of solid waste that can be disposed of improperly, reducing the useful life of the dumps. The construction waste represents a large part of Brazil's solid waste. Besides these residues there is the plastic waste classified as inert usually discarded incorrectly. In order to guide a suitable destination for these residues, the main objective of this work is to analyze the technical feasibility of the use of recycled aggregate and PET bottle particles in the manufacture of 1: 3 concrete blocks and mortars. Dimensional analysis for blocks and compressive strength at 7 and 28 days for blocks and mortars were performed. In the case of mortar, resistance was also studied at 14 days. To visualize the internal structure, the microscopic analysis was performed. In the case of the blocks, not all the analyzed samples reached the resistance required for the classification of blocks with structural function, being noticed a difference of 55% when the PET was added and 63% with the same aggregate in the mortars. In the microstructure assay it was possible to identify the largest number of voids when the PET was incorporated in the mixture. Finally, it was noticed that the insertion of the used residues brought good results in the case of 1:3 non-structural block and mortars because they reached the recommended minimum strength. |
