Abstract

Abstract

In order to study the effects of hybrid fibers on the workability and mechanical properties of rubber concrete, the slump, axial compression, splitting tensile and four-point bending tests were carried out. Taking the hybrid steel-glass fibers reinforced rubber concrete as the research object, the influence of steel fibers content, glass fibers content and glass fibers length on the workability, mechanical properties and brittle coefficient of rubber concrete was analyzed. The results showed that adding steel fibers and glass fibers decreased the workability of rubber concrete, and the influence of glass fibers were greater when the volume content was the same; as the steel fibers content increased, the mechanical properties of rubber concrete increased; as the glass fibers content increased, the mechanical properties of rubber concrete first increased and then decreased; longer glass fibers could inhibit the development of cracks more effectively, thus longer fibers improved the mechanical properties of rubber concrete more; hybrid fibers could effectively reduce the brittleness coefficient of rubber concrete and improve the toughness of rubber concrete.
