Abstract

This paper is the first part of general study started at Assiut University
dealing with effects of mineral oil on reinforced concrete structures. This
study focused on the impact of used engine oil on the compressive strength
of concrete. Compressive strength of concrete cubes soaked in used
mineral oil for six months were compared with that of oil-free concrete
cubes. Five different concrete mixes were adopted to investigate the
aggressiveness of mineral oil on low and high strength concrete.
Furthermore, this paper describes an investigation into the effect of oil
saturation on concrete frame foundations used for large machines of
Cement Assiut factory-CEMEX. It is concluded that evaluation of the
aggressive effect of mineral oil on concrete by comparing the strength on
oil-free concrete and oiled concrete at the same age experimentally is the
optimal and most reliable of the existing method. The aggressiveness of oil
is very clear for low and high strength concrete and the reduction in
compressive strength is 17, and 11.8 percent respectively. Additionally,
based on the field study, degree of oil saturation in concrete plays an
important role in compressive strength.
