Petroleum industries are recognized worldwide as an activity with major environmental impacts. One of the waste generated is the oily sludge of petroleum, produced in refineries, which contains oil and grease, heavy metals and total hydrocarbons. Thus, treatment of sludge before its disposal is necessary. This work aims to conduct the treatment of oily sludge using the technique stabilization by solidification that restricts the mobility of contaminants. The work was divided into 3 stages: experimental planning, preparation of proof bodies and evaluation of the material. Was adopted factorial design 22 where the adopted factors were: A Percentage of oily sludge and B Curing time. For factor A, percentage of residue levels were used 10% and 20 encoded down (-) and high (+), respectively. For factor B, curing time, levels were used 14 and 28 days, the encoded low levels (-) and high (+).The samples were prepared having as binder ordinary Portland cement and lime. The matrices were evaluated using the integrity and durability tests, these being, compressive strength and capacity to absorb water. It was observed that resistance to compression only the percentage of oily sludge influences the response and the water absorption capacity of the percentage of the sludge and the interaction between the curing time and the residual percentage influence on the response. All the material had a resistance value to less compression than 1 MPa, then the material must be disposed of in non-hazardous waste landfills. Regarding water absorption capacity, the material showed values below 40% which is the maximum allowable limit. .
