Effect Of Kerosene And Fuel Oil On Compressive Strength Of Reactive Powder Concrete

Abstract

The aim of this study is to investigate the effect of two of oil products(kerosene and fuel oil which is locally called black oil) on compressive strength ofreactive powder concrete. RPC was prepared using cement, silica fume, fine sand,steel fibers and superplasticizer to cast and test 63 specimens of cubes with varioussteel fibers ratios of 0%, 1% and 2% at different exposure periods in oil products (0,30, 90 and 180) days. In general the results showed that RPC has good resistance tothe effect of kerosene and fuel oil. A slight decrease in compressive strengthoccurred as the time of exposure to the oil products increase. The RPC specimens of2% steel fibers content had the lower decrease in compressive strength as a result ofthe denser microstructure. The decreasing ratio of RPC compressive strengthexposed to fuel oil (1.33%)was lower than that of kerosene (2.91%). This may beattributed to the lower viscosity of kerosene than fuel oil.
