Abstract
The aim of this study is to investigate the effect of two of oil products (kerosene and fuel oil
which is locally called as black oil) on compressive strength of reactive powder concrete (RPC).
RPC was prepared using cement, silica fume, fine sand, steel fibers and superplasticizer to cast and
test 63 specimens of cubes with various steel fibers ratios of 0%, 1% and 2% at different exposure
times in oil products (0, 30, 90 and 180) days. In general the results showed that RPC has good
resistance to the effect of kerosene and fuel oil. A slight decrease in compressive strength occurred
as the time of exposure to the oil products increases. The RPC specimens of 2% steel fibers content
had the lower decrease in compressive strength as a result of the denser microstructure. The
decreasing ratio of RPC compressive strength exposed to fuel oil (1.33%) was lower than that of
kerosene (2.91%). This may be attributed to the lower viscosity of kerosene than fuel oil.
