RPC Effect of Crude Oil Products on the Mechanical Characteristics of Reactive-Powder and Normal-Strength Concrete

This study includes detailed information on the mechanical characteristics of the hardened concrete mix for normal concrete (NSC) and reactive powder concrete (RPC) after exposure to crude oil products. Two types of crude oil products (kerosene and gas oil) were investigated after exposure for a period of 180 days. The experimental program consisted of three sets of NSC and RPC specimens; after curing all concrete specimens for 28 days and 2 days to dry in the air, the first set of specimens was immersed in kerosene for 180 days and the second set was immersed in gas oil for the same age, while the third set was left in the air as a reference set (cured normally for 28 days and tested at the age of 180 days). The results showed that the mechanical characteristics of the RPC mix were not highly affected after exposure to each type of crude oil products, where it lost about (3.41–6.32 %) compared with reference RPC mix. While the NSC mix lost about (13.82–21.95 %) of its mechanical characteristics compared with reference NSC mix after exposure to crude oil products for the same period.
