Effect of kerosene impacted sand on compressive strength of concrete in different exposure conditions

The leakage of oil products would result in contaminating the sands which are used in the concrete industry. in this study,the effect of sands contaminated with kerosene on the compressive strength of conventional normal weight concrete has been evaluated in various exposure conditions. kerosene (0,0.5,1,2,4,6 and 8%,by weight of sand) was used to contaminate sand to prepare concrete specimens. produced specimens were subjected to three exposure conditions: clean potable water (cpw),tidal environment and sea water. to evaluate the effect of kerosene soaked environment on compressive strength of concrete,a number of 12 uncontaminated samples were immersed in kerosene. the maximum strength reduction in the samples immersed in sea water was occurred. a reduction up to 27% in the concrete compressive strength was occurred in 2% kerosene contaminated samples in the all exposure conditions studied. subjecting concrete to kerosene soaked environment was not significant,however using contaminated sand adversely affect the compressive strength of concrete. careful attention in design and analysis of concrete that has been produced from kerosene contaminated sand (kcs) should be considered.
