Y-Ray Shielding Performance and Mechanical Properties of Mortar Strengthened by Amorphous Alloy Fibers

Abstract

The γ-ray shielding performance of the mortar reinforced by zirconium-based amorphous alloy fibers was studied. Meanwhile, the mechanical properties of mortar blocks with two kinds of reinforcement addition phases, i.e. amorphous alloy fibers and steel fibers were tested. The results show that the linear attenuation coefficient to γ-ray increases and the thickness of half-value layer (HVL) decreases with the increasing of volume fraction of reinforcing fibers. The shielding results were simulated by Xcom software, and proven consistent with the experimental results. The compressive strength of mortar block reinforce with fibers of 0.4% volume fraction is 5% higher than that of pure mortar, the flexural strength of mortar block reinforced with fibers of 1.2% volume fraction is 57% higher than that of pure mortar, and 33.4% higher than that of mortar block added with steel fibers.
