Tóm tắt:
Soil stabilization with binder now is a common method for treating weak soil. In this study, soft soil was mixed with geopolymer based fly ash binder to improve strength and to be environmentally friendly. Clay soil was mixed with sand to change the clay content by 24.8%, 20.4%, 14.3%, 10.2%, 6.1% and combined with fly ash geopolymer binders at the rates of 5%, 10%, 15%, 20%. Geopolymer based fly ash binder include activated alkaline solution (AAS) Na2SiO3/NaOH = 2, AAS/fly ash = 0.5. Compressive strength of soil specimens stabilized by geopolymer depends on several factors such as clay content, and geopolymer binders. The results show that clay and geopolymer binder content play an important role in the development and formation of strength of geopolymer-soil.
