RESUMO:

The disposal of polymeric waste in the environment is considered a major problem due to its low biodegradability. Low density polyethylene (LDPE) contributes as one of the main sources of pollution due to the widespread use of its products. Residues from LDPE bags, due to their properties and availability in abundance, are used in the production of precast concrete pavers. The objective of this study was to evaluate the behavior of the mechanical resistance in concrete pavers, with the incorporation of pellets from PEDB bags in the concrete mortar for making pavers (tiles) used for paving. The pellets were introduced to replace the sand, in the proportions of 10%, 20% and 30% for later comparison with specimens without replacement. Physical properties such as granulometry, mechanical compressive strength, water absorption, void ratio, dry and saturated sample density were considered to reinforce the applicability of pavers incorporated with pellets. The results showed that LDPE has the potential to be used for partial replacement of sand.
