The Mechanical Properties of Mortar Blended with Steel-PVA Hybrid Fibers and CaCO3 Whiskers Under Freeze/Thaw Cycles Condition

This research investigated the freeze/thaw cycles (0 cycles, 150 cycles, 400 cycles, and 600 cycles) influence on the mechanical properties of mortar blended with steel-PVA hybrid fibers and CaCO 3 whiskers. The freeze/thaw cycles influence was assessed through mass loss, relative dynamic elastic mo...

Summary:This research investigated the freeze/thaw cycles (0 cycles, 150 cycles, 400 cycles, and 600 cycles) influence on the mechanical properties of mortar blended with steel-PVA hybrid fibers and CaCO 3 whiskers. The freeze/thaw cycles influence was assessed through mass loss, relative dynamic elastic modulus, flexural performance, and compressive behavior. The mechanical parameters were residual flexural strength, toughness index, flexural toughness, equivalent flexural strength, post-crack strength, compressive strength increment, and compressive toughness increment. The experimental results represented that these mechanical parameters of mortar blended with CaCO 3 whiskers were higher than those without CaCO 3 whiskers under 150 cycles condition. The relative dynamic elastic modulus of mortar blended with and without CaCO 3 whiskers decreased only 4.6% and 7.5%, respectively, after 600 freeze/thaw cycles. Furthermore, a damage constitutive model containing damage variable D of mortar blended with and without CaCO 3 whiskers was established under freeze/thaw cycles conditions.
