Recycle of Construction Sludge in Soil-Cement Diaphragm Walls
Abstract:Now, the construction sludge that is produced from sites of soil-cement diaphragm walls (SMW sludge) is disposed as industrial wastes. Therefore, recycling the construction sludge brings the effective use of resource from the viewpoint of the environment preservation and also brings the reduction of the building expenses. Two ways of recycling are thought of "Recycling A; for the material of subsequent SMW it utilizes the particle muddy water that is sifted from the SMW sludge with addition of water", and "Recycling B., it utilizes the sludge with addition of water and soil stabilizer for backfill material." Recycling A could get unconfined compressive strength that was higher than the original SMW by the use of the particle muddy water. Recycling B could attain reach the target value by the SMW sludge that was adopted in the "liquefied soil stabilization." Key Words:SMW sludge, Recycling, Particle muddy water, Liquefied soil stabilization
