GREENING AND SOIL-STABILIZING MATERIAL HAVING UNSOLUBILIZING PROPERTY OF HEAVY METALS AND ENGINEERING METHOD FOR BLOWING SEED TO THICK-LAYER SUBSTRATE, METHOD FOR STABILIZING SOIL AND METHOD FOR TREATING POLLUTED SOIL BY EACH USING THE SAME MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a greening and soil-stabilizing material capable of rapidly aggregating and solidifying slurry add fertile soil and free from fear eluting heavy metals which are environmental pollution substances and provide an engineering method for blowing seeds to thick-layer substrate, an engineering method for stabilizing soil and a method for treating polluted soil by each using the material. SOLUTION: This greening and soil-stabilizing material having unsolubilizing property of heavy metals is obtained by mixing 100 pts.wt. ash component with 10-50 pts.wt. first additive composed of 1-20 wt.% aluminium sulfate, 1-20 wt.% calcium sulfate, 1-20 wt.% silica powder and 10-80 wt.% cement component and 0.2-10 pts.wt. second additive composed of 10-60 wt.% aluminium sulfate, 5-70 wt.% sodium thiosulfate and 5-50 wt.% iron powder.
