Durability of a contaminated soil treated with portland cement

Abstract


This work seeks the application of solidification/stabilization techniques to contaminated soils analyzing specifically de physical behavior of the soil through  oily sludge industrial residues and the application of that technique had an encapsulate agent, the Portland cement CP V–ARI. The tests were carried out according to NBR 13.554 (1996), and they aimed to study the level of degradation and the vulnerability of the material with several combinations of cement and acidic oily sludge as well as study their volumetric variations. Starting from the results, it is possible to observe that the larger the contamination the larger the mass loss; however the larger the amount of cement, the smaller the mass loss and the more stable the volumetric variation.
