The invention discloses a polluted site risk control barrier material and application thereof. The barrier material is prepared by mixing the following components in percentage by mass: 10-30% of a sulfate reducing bacterium agent, 10-25% of a shrimp and crab shell preparation and 45-80% of an inorganic material mixture. A low-permeability barrier can be formed in a polluted stratum, migration of underground water pollutants is efficiently blocked, effective risk management and control of polluted land parcels are achieved, and meanwhile the barrier material is convenient to apply, wide in raw material source, green and low-carbon. 本发明公开了一种污染场地风险管控阻隔材料及其应用，所述阻隔材料由以下质量百分数组分混合而成：10-30％硫酸盐还原菌菌剂，10-25％虾蟹壳制剂，45-80％无机材料混合物。其能够在污染地层中形成低渗透性的阻隔屏障，进而高效阻隔地下水污染物迁移，实现对污染地块的有效风险管控，同时阻隔材料应用便捷，原材料来源广泛，绿色低碳。
