The durability of basalt-fiber-reinforced cement mortar under exposure to unilateral salt freezing cycles

Basalt fiber and cement-based materials have been widely applied in engineering structures. In this context, the durability of basalt-fiber-reinforced ordinary silicate mortar was systematically studied under exposure to unilateral salt freezing. The mechanical durability, chloride ion diffusion characteristics, microscopic pore characteristics cement with basalt content levels range 0 kg/m 3 –1.5 were tested 0–40 freeze–thaw cycles. relationships changes internal structure mass loss, damage, physical properties material also analyzed freezing results demonstrated that even a small amount could significantly improve its resistance erosion. particular, 1.2 exhibited good compressive flexural strength, while specimens no fibers relatively large degree porosity Our work provides concrete evidence for freezing, these showing an exponential relationship loss strong linear correlation coefficient material.
