Study on Mineralogy of Stabilized Chengdu Clay by a New Stabilizer Prepared in Laboratory
详细信息   
摘要

Chengdu clay was stabilized by a new soil stabilizer prepared in laboratory. Its me- chanical properties, mineral composition and soil structure were revealed by unconfined compres- sive strength test,X-ray fluorescence and scanning electron microscope. The results show that the clay minerals in Chengdu clay were montmorillonite, llite and kaolinite, while non-clay minerals were quartz and feldspar. After stabilization, free water was converted to crystal water, and co- lumnar ettringite crystals and honeycomb or pompon-like aluminum hydroxide gels were genera- ted in the stabilized soil, forming new ettringite-clay minerals structure. The maximum unconfined compressive strength of Stabilized soil could up to 2.28 MPa. It was confirmed that Chengdu clay can be significantly reinforced by the new soil stabilizer.
