Constitutive Behavior of Clay and Pozzolan-Stabilized Hydrocarbon Refining Waste

TL;DRAbstract

A project to stabilize acidic hydrocarbon sludge lagoons for landfill deposition is described. The sludge will be microencapsulated in a clay matrix, neutralized and cemented with a lime and fly ash pozzolanic mixture. The mechanical improvement and contaminant immobilization provide dimensional stability and low leachate production rates. Two types of clay were used as the aggregate in the stabilization mixture: a spent processing attapulgite and an onsite silty clay. Results of leaching, strength, and compression tests are presented for mixtures using each clay, as is preliminary analysis of the porous monolith response to in-situ stresses.
