Researching the effect of hybrid fiber on some properties of UHPC

Abstract

UHPC is a future material of the construction industry in the 21st century. In order to be applied more and more widely in the construction industry in Vietnam, UHPC needs to achieve great efficiency in both economic and technical terms. This is influenced by many factors such as the cost of input materials, especially high-strength steel fiber reinforcement. To help improve the economic efficiency of UHPC, mixed yarns can be used. This paper presents research results on the influence of the ratio of fiber mixture composition (2 types of steel fibers) on the properties of
UHPC.

Keywords: UHPC; high strength copper clad steel fiber; 2D steel fiber; 3D steel fibe; fiber hybrid; heat moisture curing; flow; compressive strength; tensile strength.
