This research concerns the structuring of a suitable method for the removal of oil (Fuel Oil 120 cSt) from traditional bricks and Istrian Stone, materials commonly found amongst embankments and buildings of North Adriatic coastal cities. A cleaning protocol, based upon non-toxic products, was developed in consideration of its compatibility with historical, architectural surfaces. The contamination effects of oil on Istrian stone and fired clay bricks was studied, followed by a range of cleaning treatments using bulk sorbents, surfactant solutions and N,N-dimethyl-octanamide. The application was executed using the products singularly, combined or in succession. The succession of sorbent, solvent and surfactant solution demonstrated good capability of removal and was then applied on macrosamples of brick masonry showing good results.

Abstract

This research concerns the structuring of a suitable method for the removal of oil (Fuel Oil 120 cSt) from traditional bricks and Istrian Stone, materials commonly found amongst embankments and buildings of North Adriatic coastal cities. A cleaning protocol, based upon non-toxic products, was developed in consideration of its compatibility with historical, architectural surfaces. The contamination effects of oil on Istrian stone and fired clay bricks was studied, followed by a range of cleaning treatments using bulk sorbents, surfactant solutions and N,N-dimethyl-octanamide. The application was executed using the products singularly, combined or in succession. The succession of sorbent, solvent and surfactant solution demonstrated good capability of removal and was then applied on macrosamples of brick masonry showing good results.
