A series of unconfined compression tests were conducted on a riverbed silt improved with basalt fibers ordinary Portland cement. Basalt fibers of length 3, 6, 12, 20 mm and 35 mm were used in the study with different fiber contents of 0%, 0.1%, 0.3%, 0.5%, and 0.7% by weight of soil. To study the effect of curing time on strength, the specimens were cured for 7, 14, and 28 days and tested. The test results showed that the basalt fiber could effectively improve the resistance to deformation of cement-stabilized soil. The unconfined compressive strength of fiber-cement soil increased with increasing curing time. For constant fiber length, the unconfined compressive strength of fiber-cement soil increases with increasing fiber content. However, for constant fiber content, the unconfined compressive strength of fiber-cement soil did not change significantly with the increase of fiber length.
