Consequence of Kerosene Impacted Sand on Compressive Strength of Concrete in Tidal Environment

Effects of kerosene Impacted Sand on the compressive strength of concrete in tidal environment was examined. Kerosene (0, 2, 4, 6 and 8%, by weight of sand) was used to contaminate sand to prepare concrete specimens. The cubes were subjected to tidal environment in costs of Makran sea (south-east of Iran). Furthermore, other specimens subjected to clean potable water (CPW) for comparison and the compressive strengths determined at ages 3, 7, 14, 28, days. A strength reduction of 30% and 27% was shown in 2% contaminated samples subjected to Tidal and CPW. Effect of tidal environment was less significant, however using contaminated sand adversely affect the compressive strength of concrete.
