Fiber-cement composite soil

The invention discloses a fiber-cement composite soil comprising the raw materials with a ratio that: air-dried clay soil: doped amount of cement: doped amount of fly ash: doped amount of glass fiber=100:15:8:0.1. A blending method comprises the steps that: prepared air-dried clay soil and fly ash are well mixed by stirring; glass fiber is doped into the mixture and the mixture is well mixed by stirring; 50% of water is added into the mixture and the mixture is well mixed by stirring; the mixture is then placed in a sealed vessel for 24h for infiltration; the well-infiltrated mixture is fetched; a proper amount of cement and the rest 50% of water are added into the mixture; the mixture is well mixed by stirring; and the mixture is compacted and molded, wherein a water content of the fiber-cement composite soil is 14.5%. As a result of indoor preliminary tests, freezing resistance and the like of the fiber-cement composite soil are better than common cement soil, such that the fiber-cement composite soil is su
