摘要：

Effects of Crude Oil Impacted Sand (COIS) on the compressive strength of concrete was examined. Concrete mix, 1:1.8:2.7 was designed for all specimens with w/c of 0.5. Crude oil (2.5%, 5%, 10%, 15%, 20% and 25%) by weight of sand was used to contaminate sand for the preparation of COIS concrete. 147, 100 mm concrete cubes (21 control and 126 contaminated samples) were produced. The cubes were cured and the compressive strengths determined at ages 3, 7, 14, 28, 56, 84, and 168 days. COIS concrete samples showed slow rate of strength gain, and strength reduction compared with the control samples. A 18-90% compressive strength was lost due to 2.5-25% crude oil contamination, respectively. (C) 2011 Elsevier Ltd. All rights reserved.
