Abstract

Concretes were prepared containing oil sludge additive to produce new materials for construction. The oil sludge and concrete have previously been characterized in terms of chemical composition of the elements present in the materials. The concrete blocks were produced with a defined amount of oily sludge of 3.0 mass% on cement/water factor. All samples were cured at room temperature and then heated at 200 °C for 3 hours and 292 °C for 2h. The surfaces of the samples were subjected to previously grinding for the compressive strength testing. These tests were conducted in a press of 2000 kN load capacity. It was found that concrete containing additive showed a positive response in all the compressive strength tests, compared to concrete without the additive
