摘要：
The effect of inorganic soil stabilizer, as soil modifier, on the compression strength, water resistance, freeze-thaw resistance of the raw soil materials was assessed, whilst the prepared materials were characterized by means of scanning electron microscope and X-ray diffractometer. The results show that the compressive strength, softening coefficient and freeze-thaw resistance (BDR) are 8.78 MPa, 0.85 and 38.38% respectively for the raw soil material with addition of 20%~25% inorganic soil stabilizer after maintenance for 60 days, which indicates that the material has an excellent performance. The inorganic soil stabilizer reacts with SiO2 and Al2O3 in the soil to generate new products such as Ca·1.7MgO·3SiO4, 2CaO·Al2O3·SiO2 and Na2CaSiO4, in the meanwhile, α-C2S and γ-C2S within the modified admixture may react with water to produce C-S-H gel, which are the main causes responsible to the enhancement of the performance of the raw soil material. © All right reserved.
