Generally, steel fiber is broadly used to improve the mechanical and flexural strength properties of concrete, however, the steel fiber have some disadvantages including high density, fiber ball and corrosion etc. Recently, a new type of amorphous metallic fiber was developed to improve some properties of normal steel fiber such as non-corrosion and flexible properties of fiber itself.
In this paper, we used the amorphous metallic fiber with 30mm of length at additional ratios of 0%, 0.5%, 1.0%, 1.5%, 2.0%, 3.0% and 4.0% to estimate the properties of the mortar with amorphous metallic fiber. And the effects of contents of amorphous metallic fiber on the flow, compressive strength, flexural strength, drying shrinkage, crack reducing property and thermal conduction property of mortar were investigated. Test results indicated that using amorphous metallic fiber in mortar resulted in improvement in the flexural properties of mortar. The flexural strength of mortar with contents of Rf 4.0% amorphous metallic fiber was about 29% higher than that of the plain mortar. The drain shrinkage using amorphous metallic fiber was improved as compared to the mortar without the amorphous metallic fiber. In addition, the thermal conduction property was similar in all mortar mixtures regardless of contents of amorphous metallic fiber.
