Abstract
The main objective of this investigation is to study the effect of oil (kerosene, gas oil and crude oil) on the compressive and tensile strengths of high performance concrete and to compare the behavior with that of normal strength concrete. Four exposure periods were used for each specimen and for each liquid, 30, 60, 90 and 120 days after 28 days water curing. To provide a basis for comparison, reference specimens were cast and exposed to water for a
respective time of test.
The test results showed that the loss in mechanical properties (compressive and splitting tensile strengths) resulting from exposure to oil was relatively smaller for high performance concrete (HPC) compared with normal strength concrete (NSC). The difference was about 10 percent. Furthermore, the reduction in compressive and splitting tensile strengths of NSC and HPC increased with decrease in viscosity of oil in the entire period of exposure.
