This article presents an investigation on the influence of Ordinary Portland Cement (OPC) as a binder in the stabilization treatment of lateritic soil contaminated with lead or naphthalene. To evaluate the performance of the binder, the contaminated soils were tested for mechanical strength and environmental performance before and after the stabilization treatment. Results showed that the strength as inferred from the unconfined compressive strength (UCS) and cohesion values increased with the addition of the binder. Cement stabilization of the lead contaminated samples also prompted a reduction in the release of lead below the admissible limit during the leaching test. Cement stabilization of the naphthalene contaminated samples, on the other hand, could not contain the release of naphthalene below the regulatory level during the leaching test. The batch equilibrium adsorption test (BEAT) showed that cement stabilization increased the adsorption capacity of the soil for the contaminants.

铅和萘污染红土的水泥稳定化处理

本文研究了普通硅酸盐水泥 (OPC) 作为粘合剂在稳定处理铅或萘污染的红土土壤中的影响。为了评价粘结剂的性能，在稳定化处理前后对污染土壤进行机械强度和环境性能测试。结果表明，根据无侧限抗压强度 (UCS) 和内聚力值推断出的强度随着粘合剂的加入而增加。在浸出试验期间，铅污染样品的水泥稳定性也促使铅的释放量减少到允许限度以下。另一方面，在浸出测试期间，萘污染样品的水泥稳定化不能包含低于监管水平的萘释放。
