INORGANIC MATERIAL FOR GREENING AND SOIL STABILIZATION, AND THICK-LAYER BASE CONCRETE/GRASS SEED SPRAYING AND SOIL STABILIZING TECHNIQUES USING THE SAME

摘要

A material for greening and soil stabilization is prepared by mixing 100 pts. by wt. of ash with 10 to 50 pts. by wt. of an additive comprising 1 to 20 wt.% of aluminum sulfate, 1 to 20 wt.% of potassium sulfate, 1 to 20 wt.% of powdered silica and 10 to 80 wt.% of cement and at most 10 pts. by wt. of powdered ceramics. This material is mixed with a material to be planted, soil and water to form a slurried soil dressing; and the thick-layer base concrete/grass seed spraying technique using this soil dressing gives a worked surface which does not undergo soil loss by ordinary rain or deterioration by freezing, thus being advantageous to germination of the material to be planted. Further, a muddy soil can be stabilized in a short time by mixing under agitation the muddy soil with the above inorganic material and rolling the obtained mixture.
