Acesso em: 28 dez. 2022.e - 2179-0612http://repositorio.bc.ufg.br/handle/ri/21694In crushing rocks for the production of aggregates for the construction industry, a large amount of residue (artificial sand and quarry dust) is generated. The artificial sand is already used as fine aggregate replacing the natural sand of the river. The quarry dust, instead, remains stored in the courtyards of the producers of aggregates and their improper disposal can cause environmental problems and to human health. Seeking a technically and environmentally correct disposal for this waste, in this research it is studied the effect of incorporation on the mechanical properties and durability of concrete paving blocks. It was analyzed the compressive strength at 07, 28 and 90 days and the absorptions at 28 days. Six mixtures were studied: one reference mixture 1:2 (cement: total dry aggregates) (without addition of quarry dust) and five with replacement of 10% of the total aggregate for the quarry dust. It was also evaluated the effect of the addition of a plasticizer additive in the features mentioned above. The results showed that the incorporation of quarry dust was beneficial. There was an increase of resistance found in mixture 1:2 with quarry dust compared to mixture 1:2 without quarry dust. As the absorption, there was no significant difference between these mixtures. As the plasticizer additive, its effect caused significant decreases in both resistance values and the absorptions as compared to mixtures not containing additives. From the perspective of environmental protection, results were also promising considering that in all mixtures was replaced 10% of the total aggregate (sand and coarse aggregate) for quarry dust generated by the crushing of rocks.porAcesso AbertoResíduo da construçãoPó de britaPisos intertravadosBuidings wasteQuarry dustConcrete paving blocksArtigohttps://doi.org/10.5216/reec.v9i1.28021
