This invention discloses a fissure grouting material, its preparation method, and its application, belonging to the technical field of radiation protection engineering materials. By mass, its raw materials include: 45-60 parts barite sand, 25-35 parts sulfoaluminate cement, 8-20 parts borax, 2-5 parts boron carbide powder, 1-5 parts nano-gadolinium oxide, 5-15 parts lithium slag powder, 3-8 parts barium sulfate whiskers, 3-8 parts polymer emulsion, 0.5-1.5 parts water-reducing agent, 0.1-0.5 parts stabilizer, and 18-25 parts water. This invention provides high-density gamma-ray shielding through barite sand, achieves all-round neutron protection through a quaternary composite neutron absorption system, enhances the material's toughness and shielding effect through barium sulfate whiskers, and ensures high fluidity and interfacial bonding strength of the grout through the polymer emulsion. This material is particularly suitable for sealing and shielding fissures in the surrounding rock of radioactive tunnels, possessing advantages such as excellent shielding effectiveness, good construction performance, high volume stability, and long-term durability.
