To provide a lightweight aggregate storage facility capable of sufficiently suppressing any dispersion of grain size of lightweight aggregate for each sample batch taken out from the lightweight aggregate storage facility for preventing the dispersion of the quality and the capacity/weight of lightweight concrete attributable to the lightweight aggregate to be blended and used.

The lightweight aggregate storage facility has an inclined face with the angle of inclination of 15-25 with respect to a horizontal plane, and a horizontal face in contact with a lower end of the inclined face, and has lightweight aggregate take-out holes at a plurality of positions of different heights from the horizontal face and in the horizontal face.
