The application belongs to the technical field of solid waste resource utilization and anti-seepage material, and specifically provides a reactive self-healing barrier material for a phosphorus-containing contaminated site and a preparation method thereof. The material takes a base material (an alkali-activated geopolymer system, a cement-bentonite-soil system and / or a plastic concrete system) as a main body and incorporates a phosphorus fixing agent as a key functional component. The phosphorus fixing agent has the ability to adsorb and fix the seeped phosphate, which can effectively block the erosion of the bentonite structure. Meanwhile, the active ions released by the phosphorus fixing agent can react with the phosphate to generate stable minerals, which can actively fill the cracks to realize the damage self-healing of the material. The application realizes the high-value utilization of construction solid waste, and the prepared material has excellent long-term anti-seepage performance and self-repairing capacity in the phosphorus contaminated environment, and is suitable for phosphorus mine waste site blocking engineering.
