Effect of oily waste addition to clay ceramic
Source abstract
Abstract
Abstract Oily wastes are being generated in increasing amounts in the northern region of the State of Rio de Janeiro, Brazil, due to offshore petroleum extraction. More than 100 active clay ceramic industries in the region could provide a solution for the destination of such wastes by adding them to final products, mainly bricks. Thus, the effect of an oily waste obtained from a petroleum separation process on the properties of clay ceramics was investigated. The results showed that the addition of 5–10 wt.% of such oily waste produces an increase in mechanical strength, while the apparent density, linear shrinkage and water absorption remained practically unchanged. These results are not in agreement with the conclusions of a recent paper in which the incorrect interpretation of experimental data appears to be the main reason for the presented contradictions concerning the effects of oily waste additions on the properties of clay ceramics.
