Condition improvement using fiber-cement stabilized soil-based construction at Suna-
oshi river, Tamajo, Miyagi Prefecture
can also be used in a new land readjustment project for relocated victims to provide
earthquake resistant ground. In Fig.

, the improvement through using the fiber-
solidification method on the sediments is shown.

Deciding the Quantity of Paper Debris and
Performance Evaluation of Planting Base Materials
The fibrous soil solidification method involves adding to the mud/sludge shredded
paper debris and polymer additives which, after around 30 min of agitation, con-
verts a difficult to dewater sludge into a soil with good strength and deformation
properties; in the case of non-self-setting water treatment sludges, the pH can be im-
proved giving a soil which can be used for planting vegetation. The author has com-
pared the effectiveness in greening using foundation planting material produced by
the fiber solidification process on construction sludges with the normal compost
