This paper aimed to research the role of zeolite and palm fiber in changing strength of cement-treated soil. The unconfined compressive strength (UCS) testwas mainly used to study the changes of strength of cement-treated soil by varied content of cement, zeolite, palm fiber under different curing period. The optimum substitution rate of zeolite for cement was researched for the purpose of increasing of strength of cement-treated soil and low carbon and environment protection, while the optimum content of palm fiber was explored for improving of strength and ductility of cement-treated soil by means of analytic software. Finally, the multiple regression technology was used to try to capture the relationship between strength of cement-treated soil and content of zeolite and palm fiber. The results show that the cement, zeolite, palm fiber and curing age have strong effect on the UCS of cement-treated soil.
