AbstractA mixture of arsenic contaminated soil and reactive powder concrete (RPC) was developed to study the ef-fect of arsenic contaminated soil on RPC mortar and the effectiveness of the mortar in containing the con-taminant. The sufficient containment of arsenic contaminated waste products is important to protection of ground and surface water sources. A three phase experiment was designed to study the permeability, absorp-tion coefficients, and Toxicity Characteristic Leaching Procedure (TCLP) leachate concentrations resulting from the application of a range of arsenic concentrations. The results showed that the permeability values for mixes containing different arsenic concentrations did not increase noticeably with adequate curing time. The percentage of absorption slightly increased with increasing arsenic content as did the TCLP leachate concen-trations. Statistical analyses, Analysis of Variance (ANOVA) and Paired T-test, were performed to analyze percent absorption, and TCLP results. Based on the results it was concluded that percent absorption de-creased significantly with increase in curing time. Although, the TCLP concentrations increased with in-creased curing time, the increase was not statistically significant.
