The application provides a kind of ultrafine tailings cemented filling material slurry flocculation network formation time test method, and relates to the technical field of mine filling mining.The application prepares ultrafine tailings cemented filling material slurry and pure ultrafine tailings slurry body, uses dynamic rheometer to carry out strain amplitude test of fixed frequency, obtains the complement of linear viscoelastic region of two kinds of slurry body;Using dynamic rheometer, the frequency scanning test of fixed strain is carried out on the ultrafine tailings cemented filling material slurry, and the equilibrium frequency is obtained;Pre-shearing is carried out on the ultrafine tailings cemented filling material slurry, to ensure that all filling material slurries are in the same repeatable reference state;After the pre-shearing process, the time scanning test of fixed strain and frequency is directly carried out, to determine the flocculation network formation time of the ultrafine tailings cemented filling material slurry.The application helps to deeply understand the flocculation and sedimentation process of ultrafine tailings and the fluidity of ultrafine tailings cemented filling material slurry, so as to optimize the proportioning, and finally improve the utilization rate of ultrafine tailings.
