| Abstract: | The experiment was carried out with soft soil species stabilized by sulphate aluminium cement,fly ash,slag and gypsum.The mechanical property,reaction heat and microstructure of stabilized soil samples were measured.The results denote that when compound stabilizer accounts for 10 %-15 % of the soft soil total,the compressive strength is over 2.0 Mpa,the spilt strength reaches 0.5 Mpa,the quantity of heat generated is 37.5 J/g in 100hours,and the AFt and CSH generated in reaction enhances the strength of the stabilized soil. |
