Abstract
PURPOSE: To substitute hard-to-obtain natural sand by converter slag adjusted to a grain diameter of less than the specified value as fine aggregate of a hardening agent mortar.
CONSTITUTION: The converter slag adjuted to the grain diameter of 10mm or less is used as fine aggregate of the mortar hardening agent under the weak stratum solidifying treatment. Stirring shafts 2 are turned by a driving device 1 and a work performing machine A is introduced deep through the weak stratum 4 by means of stirring blades 3 located at the lower end of stirring shafts. After the work performing machine A reached a prearranged depth, it is pulled out with the stirring blades 3 caused to turn. At that time, mortar is pressure-transferred through a hollow pipe 5 with the assistance of ground mixer pump, etc. Then the mortar is drained into the underground through tips 6 located at the lower end of the hollow pipe 5, and the mortar and the weak soil are stirred and mixed, thus forming a ground treatment part 7. Because of its large specific gravity and hardness, the converter slag is useful as fine aggregate.
