Abstract

Abstract:

The low tensile strength， high brittleness， and susceptibility to cracking of cement-based materials seriously affect their durability. In order to improve the flexural bearing capacity of concrete， this study combined basalt fiber fabrics with different stacking methods， layer angles， and fabric types with concrete， and analyzed their bending properties through load-displacement curves and structural crack patterns. The results indicate that among the stacking methods， the ultimate bending load of the mesh plain weave twill stacked basalt fiber fabric reinforced concrete composite material is increased by 247.85% compared to plain concrete， while the mesh twill plain weave stacking method leads to limited reinforcement effect due to the weak interfacial bonding performance between the fabric and concrete. The ultimate bending load of the 0° layered basalt fiber mesh fabric reinforced concrete composite material reaches 611.5 N， increases by 53.64% and 39.03% compared to the 45° and 90° layered materials， respectively.Among the three fabric types， the basalt fiber plain weave fabric exhibts the most significant enhancement effect on bending strength of concrete， with ultimate bending load reaching 1 029 N. This study provide a technical support for the structure design and mechanical analysis of flexural-resistant structures using basalt fiber fabric reinforced cement-based composite materials in the field of building reinforcement.
