Several studies have pointed out that there was a linear relationship between the tensile strength and the compressive strength of the cement soil [32,33]. Therefore, the correlation between the splitting tensile strength and the compressive strength of the cement soil reinforced with basalt fibers was investigated in this study.

After 100 cycles, the triaxial compressive strength of the basalt decreased by 29.5% at a confining pressure of 2 MPa, 29.3% at 4 MPa, and 31.5% at 6 MPa. It is evident that the samples that had not undergone any freeze-thaw cycles exhibited the highest strength. However, with the increase in the number of freeze-thaw cycles, there was a ...

As the 7-day compressive strength of the 8–0 series composites was relatively low at 4.88 MPa, it can be inferred that fiber reinforcement had a positive effect on the compressive strength of the composites. However, a decline in compressive strength was observed as the fiber content increased from 0.5 to 1.0%.
