  • Modified expanded polystyrene particles, modification method thereof, concrete containing modified expanded polystyrene
    Patent number: 11732103
    Abstract: Disclosed are modified expanded polystyrene (EPS) particles and a modification method thereof, and concrete containing the modified EPS particles and a preparation method thereof, relating to the technical field of inorganic building materials. The modification method of the EPS particles includes following steps: (1) spraying adhesive materials on surfaces of the EPS particles in a stirring state, and obtaining the EPS particles with the adhesive materials attached to the surfaces; and (2) mixing the EPS particles attached with the adhesive materials with inorganic mixed materials to obtain the modified EPS particles. The preparation method of modified EPS concrete includes: mixing the modified EPS particles with a cementitious material, adding an admixture and water, and uniformly stirring to obtain the modified EPS concrete.
