Avaliação da granulometria de resíduo cerâmico para utilização em camadas de sub-base de pavimento de baixo volume de tráfego.

Abstract

The inadequate waste disposal is becoming a point of concern every day, as they have a great contribution in environmental pollution and, in virtue of this, researchers have been looking for alternatives to their uses. In the red ceramics industry there is a great amount of waste produced and, therefore, it has been and continues to be the focus of many researches related to the civil construction sector, such as in the production of mortars, in the block production process, as well as in layers of pavement support. This research evaluated the use of red ceramic residue due to failure of processing and storage breaks. For that, three soil-residue mixtures were studied, which will have a granulometry of the residue with a 50% substitution percentage, in the mixture with the soil for use in low-traffic-volume pavement sub-grade. Compaction tests were carried out in the Proctor Intermediate energy and CBR, and it was observed that the mixture with residue in the size range retained between the sieves of the No. 80 and No. 200 sieves generated 62.39% increase in the CBR value of the reference sample (soil), resulting in 18.35%, although it did not reach the minimum value recommended by the standard of 20%;
