Abstract:
This paper presents an experimental investigation that evaluates the potential of using benzene contaminated soils as a fine aggregate replacement in concrete. Two different soil types were used; well-graded sand and silty sand. Soils were artificially contaminated with benzene at concentration levels of 0.5 and 3 percent by weight. The artificially contaminated soils (ACS) were used to replace sand (fine aggregate) in concrete mixtures at two replacement levels; 40 and 80 percent by weight. The resulting concrete mixtures were tested for setting times, compressive strength, stiffness, permeability, and durability to freezing and thawing. Five reinforced concrete beams were made with ACS mixtures and tested to failure under flexure loading. The findings indicate that when using well-graded sand, the resulting concrete demonstrates acceptable levels of performance. However, when silty sand is used, less favorable results are obtained.
