This research discusses the main factors effecting the permeability reduction due to cement infiltration or top soil masking when cement infiltrates in a river sediment matrix. This is relevant to the migration of pollutants to the groundwater through surface water infiltration, which is an important and urgent problem to resolve. A series of indoor infiltration simulations were performed to measure the infiltration reduction when the cement infiltrate in a selected soil matrix under different conditions (e.g. dry density, postponing time and waterhead, etc.). The infiltration in the cement-treated samples was compared with a reference infiltration with no cement masking or infiltrating. It was found that the infiltration rates of the cement-treated soils were consistently lower than the control sample, indicating an infiltration reduction due to cement infiltration. The average reduction ranged 3.59-44.33% depending on different processing methods. In this paper, some main factors affecting the permeability-reducing effect of cement infiltration in a river sediment matrix, such as the soil texture, dry density, postponing time of water supply, initial waterhead, and cement addition quantity, are discussed, and theories regarding cement infiltration mechanisms are presented
