Creators

  • 1. Hitachi Ltd., Tokyo (Japan)

Description

During or after injection of a solidifier to a vessel filled with wastes, a portion of gaps is replaced with the solidifier material by applying vibrations to the vessel and then the solidifier is again charged by an amount corresponding to level reduction of the solidifier. With such procedures, solidification products with less porosity having excellent strength and durability can be formed. (T.M.)
