Recently, researchers are trying to incorporate alternative fuels and raw materials (AFR) to produce different types of cement like Ordinary Portland Cement (OPC), Portland Pozzolana Cement (PPC), Low Heat Cement and others. This incorporation is to avoid harmful impacts of AFR and to produce alternative sustainable cement. In this study, petroleum sludge (PS) waste, which is a type of AFR, was assessed to be incorporated into cement production as a sustainable treatment method for this waste that could also provide a low cost production of cement. To achieve the assessment method, PS was characterized for its physical, chemical and gas emission features to provide the advantages of its use as an ingredient to decrease the consumption of raw materials as well as the fuel within the cement plants. After characterization, 1%, 2.5% and 5% of PS was blended with the cement raw materials. Then, the prepared samples were incinerated within an electric furnace in order to produce the cement. After that, the cement produced was subjected to different chemical, structural, morphological and other analyses. The findings through this research were promising and the incorporation of petroleum sludge into cement plant could provide a sustainable low cost treatment method for this waste. The results showed that incorporation of 2.5% of petroleum sludge into cement production was considered as optimum and could produce an adequate and an acceptable quality of cement. This incorporation was able to decrease 2.5% of the cement raw materials and provided 2.1% to 2.4% of the energy required to produce cement. This research provides a sustainable low cost treatment method of PS that offer ultimate elimination of this waste by offering a decrease in the raw materials and a decrease in the fuel needed to produce cement.
