    • PURPOSE: Provided is an environment-friendly hardener, a mixture of Ca, Al and Si-compound, to solidify soil rapidly by using limestone, clay and bauxite as raw materials. The resultant hardener offers high strength, cracking prevention and rapid solidification for short-time working. CONSTITUTION: The hardener, being instead of cement, for soil solidification is prepared by mixing mixture(A) and mixture(B). The mixture(A) is obtained by mixing 100pts.wt. of lime stone with 50pts.wt. of clay and sintering at 1100deg.C for 1-2hrs. The mixture(B) is obtained by the following steps; melting 50pts.wt. of bauxite and flux(10pts.wt. of NaOH + 30pts.wt. of CaO) at 850deg.C; adding 10% of dilute HNO3 for a slurry, and adjust pH of the slurry between 6-8; adding 10pts.wt. of silica fume; evaporate drying and sintering at 600deg.C for 4hrs. The 10pts.wt. of prepared hardener is mixed with 90pts.wt. of soil and yellow earth for constructional use.
